2.1.2. Internal Configuration
You need to program the configuration data into the configuration flash memory (CFM)
before internal configuration can take place. The configuration data to be written to
CFM will be part of the programmer object file (.pof). Using JTAG In-System
Programming (ISP), you can program the .pof into the internal flash.
During internal configuration, Intel MAX 10 devices load the CRAM with configuration
data from the CFM.

2.1.2.2. Configuration Flash Memory
The CFM is a non-volatile internal flash that is used to store configuration images. The
CFM may store up to two compressed configuration images, depending on the
compression and the Intel MAX 10 devices. The compression ratio for the configuration
image should be at least 30% for the device to be able store two configuration
images.

Configuration Flash Memory Permissions on page 23
2.1.2.2.1. Configuration Flash Memory Sectors
All CFM in Intel MAX 10 devices consist of three sectors, CFM0, CFM1, and CFM2
except for the 10M02. The sectors are programmed differently depending on the
internal configuration mode you select.
The 10M02 device consists of only CFM0. The CFM0 sector in 10M02 devices is
programmed similarly when you select single compressed image or single
uncompressed image.

Devices
Note: The programming time reflects JTAG interface programming time only without any system
overhead. It does not reflect the actual programming time that you face. To compensate the
system overhead, Intel Quartus Prime Programmer is enhanced to utilize flash parallel mode
during device programming for Intel MAX 10 10M04/08/16/25/40/50 devices. The 10M02
device does not support flash parallel mode, you may experience a relatively slow
programming time if compare to other device.

2.1.2.3. In-System Programming
You can program the internal flash including the CFM of Intel MAX 10 devices with ISP
through industry standard IEEE 1149.1 JTAG interface. ISP offers the capability to
program, erase, and verify the CFM. The JTAG circuitry and ISP instructions for Intel
MAX 10 devices are compliant to the IEEE-1532-2002 programming specification.
During ISP, the Intel MAX 10 receives the IEEE Std. 1532 instructions, addresses, and
data through the TDI input pin. Data is shifted out through the TDO output pin and
compared with the expected data.
The following are the generic flow of an ISP operation:
1. Check ID—the JTAG ID is checked before any program or verify process. The time
required to read this JTAG ID is relatively small compared to the overall
programming time.
2. Enter ISP—ensures the I/O pins transition smoothly from user mode to the ISP
mode.
3. Sector Erase—shifting in the address and instruction to erase the device and
applying erase pulses.
4. Program—shifting in the address, data, and program instructions and generating
the program pulse to program the flash cells. This process is repeated for each
address in the internal flash sector.
5. Verify—shifting in addresses, applying the verify instruction to generate the read
pulse, and shifting out the data for comparison. This process is repeated for each
internal flash address.
6. Exit ISP—ensures that the I/O pins transition smoothly from the ISP mode to the
user mode.
You can also use the Intel Quartus Prime Programmer to program the CFM.

Provides the steps to program the .pof using Intel Quartus Prime Programmer.
2.1.2.3.1. ISP Clamp
When a normal ISP operation begins, all I/O pins are tri-stated. For situations when
the I/O pins of the device should not be tri-stated when the device is in ISP operation,
you can use the ISP clamp feature.
When the ISP clamp feature is used, you can set the I/O pins to tri-state, high, low, or
sample and sustain. The Intel Quartus Prime software determines the values to be
scanned into the boundary-scan registers of each I/O pin, based on your settings. This
will determine the state of the pins to be clamped to when the device programming is
in progress.
Before clamping the I/O pins, the SAMPLE/PRELOAD JTAG instruction is first executed
to load the appropriate values to the boundary-scan registers. After loading the
boundary-scan registers with the appropriate values, the EXTEST instruction is
executed to clamp the I/O pins to the specific values loaded into the boundary-scan
registers during SAMPLE/PRELOAD.
If you choose to sample the existing state of a pin and hold the pin to that state when
the device enters ISP clamp mode, you must ensure that the signal is in steady state.
A steady state signal is needed because you cannot control the sample set-up time as
it depends on the TCK frequency as well as the download cable and software. You
might not capture the correct value when sampling a signal that toggles or is not
static for long periods of time.

2.1.2.3.2. Real-Time ISP
In a normal ISP operation, to update the internal flash with a new design image, the
device exits from user mode and all I/O pins remain tri-stated. After the device
completes programing the new design image, it resets and enters user mode.
The real-time ISP feature updates the internal flash with a new design image while
operating in user mode. During the internal flash programming, the device continues
to operate using the existing design. After the new design image programming
process completes, the device will not reset. The new design image update only takes
effect in the next reconfiguration cycle.

2.1.2.3.3. ISP and Real-Time ISP Instructions
Table 5. ISP and Real-Time ISP Instructions for Intel MAX 10 Devices
Instruction Instruction Code Description
CONFIG_IO 00 0000 1101 Allows I/O reconfiguration through JTAG ports using the
IOCSR for JTAG testing. This is executed after or during
configurations.
nSTATUS pin must go high before you can issue the
CONFIG_IO instruction.
PULSE_NCONFIG 00 0000 0001 Emulates pulsing the nCONFIG pin low to trigger reconfiguration
even though the physical pin is unaffected.
ISC_ENABLE_HIZ (1)10 1100 1100 Puts the device in ISP mode, tri-states all I/O pins, and drives
all core drivers, logic, and registers.
Device remains in the ISP mode until the ISC_DISABLE
instruction is loaded and updated.
The ISC_ENABLE instruction is a mandatory instruction. This
requirement is met by the ISC_ENABLE_CLAMP or
ISC_ENABLE_HIZ instruction.
ISC_ENABLE_CLAMP (1)10 0011 0011 Puts the device in ISP mode and forces all I/O pins to follow
the contents of the JTAG boundary-scan register.
When this instruction is activated, all core drivers, logics, and
registers are frozen. The I/O pins remain clamped until the
device exits ISP mode successfully.
ISC_DISABLE 10 0000 0001 Brings the device out of ISP mode.
Successful completion of the ISC_DISABLE instruction
happens immediately after waiting 200 µs in the Run-Test/Idle
state.
ISC_PROGRAM(2)10 1111 0100 Sets the device up for in-system programming. Programming
occurs in the run-test or idle state.
ISC_NOOP(2)10 0001 0000 Sets the device to a no-operation mode without leaving the
ISP mode and targets the ISC_Default register.
Use when:
two or more ISP-compliant devices are being accessed in
ISP mode and;
a subset of the devices perform some instructions while
other more complex devices are completing extra steps in
a given process.
ISC_ADDRESS_SHIFT(2)10 0000 0011 Sets the device up to load the flash address. It targets the
ISC_Address register, which is the flash address register.
ISC_ERASE(2)10 1111 0010 Sets the device up to erase the internal flash.

Instruction Instruction Code Description
ISC_READ(2)10 0000 0101 Sets the device up for verifying the internal flash under
normal user bias conditions.
The ISC_READ instruction supports explicit addressing and
auto-increment, also known as the Burst mode.
BGP_ENABLE 01 1001 1001 Sets the device to the real-time ISP mode.
Allows access to the internal flash configuration sector while
the device is still in user mode.
BGP_DISABLE 01 0110 0110 Brings the device out of the real-time ISP mode.
The device has to exit the real-time ISP mode using the
BGP_DISABLE instruction after it is interrupted by
reconfiguration.
Caution: Do not use unsupported JTAG instructions. It will put the device into an unknown state
and requires a power cycle to recover the operation.

The remote system upgrade feature detects errors in the following sequence:
1. After power-up, the device samples the CONFIG_SEL pin to determine which
application configuration image to load. The CONFIG_SEL pin setting can be
overwritten by the input register of the remote system upgrade circuitry for the
subsequent reconfiguration.
2. If an error occurs, the remote system upgrade feature reverts by loading the other
application configuration image. These errors cause the remote system upgrade
feature to load another application configuration image:
Internal CRC error
User watchdog timer time-out
3. Once the revert configuration completes and the device is in user mode, you can
use the remote system upgrade circuitry to query the cause of error and which
application image failed.
4. If a second error occurs, the device waits for a reconfiguration source. If the
Auto-restart configuration after error is enabled, the device will reconfigure
without waiting for any reconfiguration source.
5. Reconfiguration is triggered by the following actions:

Description
RU_DIN regin Input Use this signal to write data to the shift register on the rising edge of
RU_CLK. To load data to the shift register, assert RU_SHIFTnLD.
RU_DOUT regout Output
Use this signal to get output data from the shift register. Data is
clocked out on each rising edge of RU_CLK if RU_SHIFTnLD is
asserted.
RU_nRSTIMER rsttimer Input
Use this signal to reset the user watchdog timer. A falling edge of
this signal triggers a reset of the user watchdog timer.
To reset the timer, pulse the RU_nRSTIMER signal for a minimum of
250 ns.
RU_nCONFIG rconfig Input
Use this signal to reconfigure the device. Driving this signal low
triggers the device to reconfigure if you enable the remote system
upgrade feature.
RU_CLK clk Input
The clock to the remote system upgrade circuitry. All registers in this
clock domain are enabled in user mode if you enable the remote
system upgrade. Shift register and input register are positive edge flip-
flops.
RU_SHIFTnLD shiftnld Input Control signals that determine the mode of remote system upgrade
circuitry.
When RU_SHIFTnLD is driven low and RU_CAPTnUPDT is driven
low, the input register is loaded with the contents of the shift
register on the rising edge of RU_CLK.
When RU_SHIFTnLD is driven low and RU_CAPTnUPDT is driven
high, the shift register captures values from the input_cs_ps
module on the rising edge of RU_CLK.
When RU_SHIFTnLD is driven high, the RU_CAPTnUPDT will be
ignored and the shift register shifts data on each rising edge of
RU_CLK.

2.2.2.1. AES Encryption Protection
The Intel MAX 10 design security feature provides the following security protection for
your designs:
Security against copying—the non-volatile key is securely stored in the Intel MAX
10 devices and cannot be read through any interface. Without this key, attacker
will not be able to decrypt the encrypted configuration image.
Security against reverse engineering—reverse engineering from an encrypted
configuration file is very difficult and time consuming because the file requires
decryption.
Security against tampering—after you enable the JTAG Secure and Encrypted POF
(EPOF) only, the Intel MAX 10 device can only accept configuration files encrypted
with the same key. Additionally, configuration through the JTAG interface is
blocked.

and then encrypted using the Intel Quartus Prime software. During configuration, the
device first decrypts, and then decompresses the configuration file.

At the initial state, the data_valid signal is low because no data is read from the
unique chip ID block. After feeding a clock signal to the clkin input port, the Unique
Chip ID Intel FPGA IP core begins to acquire the chip ID of your device through the
unique chip ID block. After acquiring the chip ID of your device, the Unique Chip ID
Intel FPGA IP core asserts the data_valid signal to indicate that the chip ID value at
the output port is ready for retrieval.
The operation repeats only when you provide another clock signal when the
data_valid signal is low. If the data_valid signal is high when you provide
another clock signal, the operation stops because the chip_id[63..0] output holds
the chip ID of your device.
A minimum of 67 clock cycles are required for the data_valid signal to go high.

2.2.3. SEU Mitigation and Configuration Error Detection
The dedicated circuitry built in Intel MAX 10 devices consists of an error detection
cyclic redundancy check (EDCRC) feature. You can use this feature to mitigate single-
event upset (SEU) or soft errors.
The hardened on-chip EDCRC circuitry allows you to perform the following operations
without any impact on the fitting of the device:
Auto-detection of cyclic redundancy check (CRC) errors during configuration.
Identification of SEU in user mode with the optional CRC error detection.
Testing of error detection by error detection verification through the JTAG
interface.

2.2.3.1. Configuration Error Detection
In configuration mode, a frame-based CRC is stored in the configuration data and
contains the CRC value for each data frame.
During configuration, the Intel MAX 10 device calculates the CRC value based on the
frame of data that is received and compares it against the frame CRC value in the data
stream. Configuration continues until the device detects an error or when all the
values are calculated.
For Intel MAX 10 devices, the CRC is computed by the Intel Quartus Prime software
and downloaded into the device as part of the configuration bit stream. These devices
store the CRC in the 32-bit storage register at the end of the configuration mode.
2.2.3.2. User Mode Error Detection
SEUs are changes in a CRAM bit state due to an ionizing particle. Intel MAX 10 devices
have built-in error detection circuitry to detect data corruption in the CRAM cells.
This error detection capability continuously computes the CRC of the configured CRAM
bits. The CRC of the contents of the device are compared with the pre-calculated CRC
value obtained at the end of the configuration. If the CRC values match, there is no
error in the current configuration CRAM bits. The process of error detection continues
until the device is reset—by setting nCONFIG to low.
The error detection circuitry in Intel MAX 10 device uses a 32-bit CRC IEEE Std. 802
and a 32-bit polynomial as the CRC generator. Therefore, the device performs a single
32-bit CRC calculation. If an SEU does not occur, the resulting 32-bit signature value is
0x000000, which results in a 0 on the output signal CRC_ERROR. If an SEU occurs in
the device, the resulting signature value is non-zero and the CRC_ERROR output signal
is 1. You must decide whether to reconfigure the FPGA by strobing the nCONFIG pin
low or ignore the error.

CRC_ERROR
There are two sets of 32-bit registers in the error detection circuitry that store the
computed CRC signature and pre-calculated CRC value. A non-zero value on the
signature register causes the CRC_ERROR pin to go high.
Table 18. Error Detection Registers for Intel MAX 10 Devices
Register Description
32-bit signature
register
This register contains the CRC signature. The signature register contains the result of the user
mode calculated CRC value compared against the pre-calculated CRC value. If no errors are
detected, the signature register is all zeros. A non-zero signature register indicates an error in the
configuration CRAM contents. The CRC_ERROR signal is derived from the contents of this register.
32-bit storage register
This register is loaded with the 32-bit pre-computed CRC signature at the end of the configuration
stage. The signature is then loaded into the 32-bit Compute and Compare CRC block during user
mode to calculate the CRC error. This register forms a 32-bit scan chain during execution of the
CHANGE_EDREG JTAG instruction. The CHANGE_EDREG JTAG instruction can change the content of
the storage register. Therefore, the functionality of the error detection CRC circuitry is checked in-
system by executing the instruction to inject an error during the operation. The operation of the
device is not halted when issuing the CHANGE_EDREG JTAG instruction.
2.2.3.2.2. CHANGE_EDREG JTAG Instruction
Table 19. CHANGE_EDREG JTAG Instruction Description
JTAG Instruction Instruction Code Description
CHANGE_EDREG 00 0001 0101 This instruction connects the 32-bit CRC storage register between TDI
and TDO. Any precomputed CRC is loaded into the CRC storage register
to test the operation of the error detection CRC circuitry at the
CRC_ERROR pin.
2.2.3.3. Error Detection Timing
When the error detection CRC feature is enabled through the Intel Quartus Prime
software, the device automatically activates the CRC process upon entering user
mode, after configuration and initialization is complete.

The CRC_ERROR pin will remain low until the error detection circuitry has detected a
corrupted bit in the previous CRC calculation. After the pin goes high, it remains high
during the next CRC calculation. This pin does not log the previous CRC calculation. If
the new CRC calculation does not contain any corrupted bits, the CRC_ERROR pin is
driven low. The error detection runs until the device is reset.
The error detection circuitry is clocked by an internal configuration oscillator with a
divisor that sets the maximum frequency. The CRC calculation time depends on the
device and the error detection clock frequency.

For 10M16 device with divisor value of 256:
Minimum CRC calculation time for divisor 256 = 10 x (256/2) = 1280 ms
2.2.3.4. Recovering from CRC Errors
The system that Intel MAX 10 resides in must control device reconfiguration. After
detecting an error on the CRC_ERROR pin, strobing the nCONFIG pin low directs the
system to perform reconfiguration at a time when it is safe for the system to
reconfigure the Intel MAX 10 device.
When the data bit is rewritten with the correct value by reconfiguring the device, the
device functions correctly.
While SEUs are uncommon in Intel FPGA devices, certain high-reliability applications
might require a design to account for these errors.
2.2.4. Configuration Data Compression
Intel MAX 10 devices can receive compressed configuration bitstream and decompress
the data in real-time during configuration. This feature helps to reduce the
configuration image size stored in the CFM. Data indicates that compression typically
reduces the configuration file size by at least 30% depending on the design.

JTAG pins:
If you intend to switch back and forth between user I/O pins and JTAG pin functions using the
JTAGEN pin, all JTAG pins must be assigned as single-ended I/O pins or voltage-referenced I/O
pins. Schmitt trigger input is the recommended input buffer.
JTAG pins cannot perform as JTAG pins in user mode if you assign any of the JTAG pin as a
differential I/O pin.
You must use the JTAG pins as dedicated pins and not as user I/O pins during JTAG programming.
Do not toggle JTAG pin during the initialization stage.
Put the test access port (TAP) controller in reset state by driving the TDI and TMS pins high and
TCK pin low for at least 5 clock cycles before the initialization.
The Signal Tap logic analyzer IP, JTAG-to-Avalon master bridge IP, and other JTAG-related IPs

To configure a device in a JTAG chain, the programming software sets the other
devices to bypass mode. A device in bypass mode transfers the programming data
from the TDI pin to the TDO pin through a single bypass register. The configuration
data is available on the TDO pin one clock cycle later.

The Intel Quartus Prime software uses the CONF_DONE pin to verify the completion of
the configuration process through the JTAG port:
CONF_DONE pin is low—indicates that the configuration has failed.
CONF_DONE pin is high—indicates that the configuration was successful.
After the configuration data is transmitted serially using the JTAG TDI port, the TCK
port is clocked to perform device initialization.
Preventing Voltage Overshoot
To prevent voltage overshoot, you must use external diodes and capacitors if
maximum AC voltage for both VCCIO and JTAG header exceed 3.9V. However, Intel
recommends that you use the external diodes and capacitors if the supplies exceed
2.5V.
JTAGEN
If you use the JTAGEN pin, Intel recommends the following settings:
Once you entered user mode and JTAG pins are regular I/O pins—connect the
JTAGEN pin to a weak pull-down (1 kΩ).
Once you entered user mode and JTAG pins are dedicated pins—connect the
JTAGEN pin to a weak pull-up (10 kΩ).
Note: Intel recommends that you use three-pin header with a jumper or other switching
mechanism to change the JTAG pins behavior.
3.2.4. ICB Settings in JTAG Configuration
The ICB settings are loaded into the device during .pof programming of the internal
configuration scheme. The .sof used during JTAG configuration programs the CRAM
only and does not contain ICB settings. The Intel Quartus Prime Programmer will
make the necessary setting based on the following:
Device without ICB settings—ICB settings cleared from the internal flash or new
device
Device with ICB settings—prior ICB settings programmed using .pof
Devices without ICB Settings
For devices without ICB settings, the default value will be used. However, Intel
Quartus Prime Programmer disables the user watchdog timer by setting the Watchdog
Timer Enable bit to 0. This step is to avoid any unwanted reconfiguration from
occurring due to user watchdog timeout.
If the default ICB setting is undesired, you can program the desirable ICB setting first
by using .pof programming before doing the JTAG configuration.
Devices with ICB Settings
For device with ICB settings, the settings will be preserved until the internal flash is
erased. You can refer to the .map file to view the preserved ICB settings. JTAG
configuration will follow the preserved ICB setting and behave accordingly.

3.6. Error Detection
3.6.1. Verifying Error Detection Functionality
You can inject a soft error by changing the 32-bit CRC storage register in the CRC
circuitry. After verifying the failure induced, you can restore the 32-bit CRC value to
the correct CRC value using the same instruction and inserting the correct value. Be
sure to read out the correct value before updating it with a known bad value.
In user mode, Intel MAX 10 devices support the CHANGE_EDREG JTAG instruction,
which allows you to write to the 32-bit storage register. You can use .jam to automate
the testing and verification process. You can only execute this instruction when the
device is in user mode. This instruction enables you to dynamically verify the CRC
functionality in-system without having to reconfigure the device. You can then switch
to use the CRC circuit to check for real errors induced by an SEU.
After the test completes, you can clear the CRC error and restore the original CRC
value using one of the following methods:

Perform these steps:
1. After the configuration completes, use CHANGE_EDREG JTAG instruction to
shift out the correct precomputed CRC value and load the wrong CRC value to
the CRC storage register. When an error is detected, the CRC_ERROR pin will
be asserted.
2. Use CHANGE_EDREG JTAG instruction to shift in the correct precomputed CRC
value. The CRC_ERROR pin is de-asserted to show that the error detection CRC
circuitry is working.

3.6.3. Accessing Error Detection Block Through User Logic
The error detection circuit stores the computed 32-bit CRC signature in a 32-bit
register. The user logic from the core reads out this signature. The
fiftyfivenm_crcblock primitive is a WYSIWYG component used to establish the
interface from the user logic to the error detection circuit. The
fiftyfivenm_crcblock primitive atom contains the input and output ports that
must be included in the atom. To access the logic array,you must insert the
fiftyfivenm_crcblock WYSIWYG atom into your design. The recommended clock
frequency of .clk port is to follow the clock frequency of EDCRC block.

Definition
<crcblock_name> Unique identifier for the CRC block and represents any identifier name that is
legal for the given description language such as Verilog HDL, VHDL, AHDL. This
field is required.
.clk(<clock source> Input This signal designates the clock input of this cell. All operations of this cell are
with respect to the rising edge of the clock. Whether it is the loading of the data
into the cell or data out of the cell, it always occurs on the rising edge. This port
is required.
.shiftnld (<shiftnld
source>)
Input This signal is an input into the error detection block. If shiftnld=1, the data is
shifted from the internal shift register to the regout at each rising edge of clk. If
shiftnld=0, the shift register parallel loads either the pre-calculated CRC value
or the update register contents depending on the ldsrc port input. This port is
required.
.ldsrc (<ldsrc
source>)
Input This signal is an input into the error detection block. If ldsrc=0, the pre-
computed CRC register is selected for loading into the 32-bit shift register at the
rising edge of clk when shiftnld=0. Ifldsrc=1, the signature register (result
of the CRC calculation) is selected for loading into the shift register at the rising
edge of clk when shiftnld=0. This port is ignored when shiftnld=1. This
port is required.
.crcerror (<crcerror
out destination>)
Output This signal is the output of the cell that is synchronized to the internal oscillator
of the device (100-MHz or 80-MHz internal oscillator) and not to the clk port. It
asserts automatically high if the error block detects that a SRAM bit has flipped
and the internal CRC computation has shown a difference with respect to the
pre-computed value. This signal must be connected either to an output pin or a
bidirectional pin. If it is connected to an output pin, you can only monitor the
CRC_ERROR pin (the core cannot access this output). If the CRC_ERROR signal is
used by core logic to read error detection logic, this signal must be connected to
a BIDIR pin. The signal is fed to the core indirectly by feeding a BIDIR pin that
has its oe port connected to VCC.
.regout (<output
destination>)
Output This signal is the output of the error detection shift register synchronized to the
clk port, to be read by core logic. It shifts one bit at each cycle. User should
clock the clk signal 31 cycles to read out the 32 bits of the shift register. The
values at the .regout port are an inversion of the actual values.

3.7. Enabling Data Compression
When you enable compression, the Intel Quartus Prime software generates
configuration files with compressed configuration data.
A compressed configuration file is needed to use the dual configuration mode in the
internal configuration scheme. This compressed file reduces the storage requirements
in internal flash memory, and decreases the time needed to send the bitstream to the
Intel MAX 10 device family. There are two methods to enable compression for the Intel
MAX 10 device family bitstreams in the Intel Quartus Prime software:
Before design compilation—using the Compiler Settings menu.
After design compilation—using the Convert Programming Files option.
3.7.1. Enabling Compression Before Design Compilation

3.9.1. Internal and External JTAG Interfaces
There are two interfaces to access the JTAG control block in Intel MAX 10 devices:
External JTAG interface—connection of the JTAG control block from the physical
JTAG pins; TCK, TDI, TDO, and TMS.
Internal JTAG interface—connection of the JTAG control block from the internal
FPGA core fabric.
You can only access the JTAG control block using either external or internal JTAG
interface one at a time. External JTAG interfaces are commonly used for JTAG
configuration using programming cable. To access the internal JTAG interface, you
must include the JTAG WYSIWYG atom in your Intel Quartus Prime software design.

To disable the JTAG Secure mode, trigger the start_unlock port of the user logic to
issue the UNLOCK JTAG instruction. After the UNLOCK JTAG instruction is issued, the
device exits from JTAG secure mode. When the JTAG Secure mode is disabled, you can
choose to full-chip erase the internal flash of Intel MAX 10 device to disable the JTAG
Secure mode permanently.
The start_lock port in the user logic triggers the execution of the LOCK JTAG
instruction. Executing this instruction enables the JTAG Secure mode of the Intel MAX

3.9.4. Verifying the JTAG Secure Mode
You can verify whether your device has successfully entered or exited JTAG secure
mode by executing a non-mandatory JTAG instruction.
Note: You must instantiate the internal JTAG interface for you unlock the external JTAG when
the device is in JTAG Secure mode.
When you enable the JTAG Secure option, the Intel MAX 10 device will be in the JTAG
Secure mode after power-up. To validate the JTAG Secure feature in your design
example, perform these steps:
1. Configure the reference design .pof file into the device with JTAG Secure mode
enabled. After power cycle, the device should be in JTAG Secure mode.
2. You can ensure that the device enters user mode successfully by observing one of
the following:
CONFDONE pin goes high
counter_output pin starts toggling
3. Issue the PULSE_NCONFIG JTAG instruction using the external JTAG pins to
reconfigure the device. You can use the pulse_ncfg.jam file attached in the
design example. To execute the pulse_ncfg.jam file, you can use the
quartus_jli or the JAM player. You can ensure that the device does not reconfigure
by observing one of the following:
CONFDONE pin stays high
counter_output pin continues toggling
Unsuccessful reconfiguration verifies that the device is currently in JTAG Secure
mode.
4. Pull the start_unlock port of the user logic to logic high to execute the UNLOCK
JTAG instruction.
The indicator port goes high after the UNLOCK JTAG instruction is complete.
5. Issue the PULSE_NCONFIG JTAG instruction using the external JTAG pins to
reconfigure the device. You can ensure that the device reconfigures successfully
by observing one of the following:
CONFDONE pin is low
counter_output pin stops toggling
Successful reconfiguration verifies that the device is currently not in JTAG Secure
mode.

the IP core.
data_valid Output 1 Indicates that the unique chip ID is ready for retrieval. If
the signal is low, the IP core is in initial state or in
progress to load data from a fuse ID.
After the IP core asserts the signal, the data is ready for
retrieval at the chip_id[63..0] output port.
chip_id Output 64 Indicates the unique chip ID according to its respective
fuse ID location. The data is only valid after the IP core
asserts the data_valid signal.
The value at power-up resets to 0.
