DESCRIPTION
Firmware Version. 8 bits of memory for user-defined firmware version number.
Configuration Lock:
[0]
Write a ‘1’ to r5Fh[0] to toggle this register bit.
0 = Register and EEPROM configuration unlocked.
1 = Register and EEPROM configuration locked.

Fault Log EEPROM Lock Flag (set automatically after fault log is triggered):
Write a ‘1’ to r5Fh[1] to toggle this register bit.
0 = EEPROM is not locked. A triggered fault log stores fault information to EEPROM.
1 = A fault log has been triggered. Write a ‘1’ to this bit to clear the flag and allow a
new fault log to be triggered.
Not used.

patible serial bus. Either interface may be used to access
internal memory; however, only one interface is allowed to
run at a time. All digital I/Os on the MAX16031/MAX16032
are IEEE 1149.1 boundary-scan compliant, and contain
the typical JTAG boundary scan cells that allow the
inputs/outputs to be polled or forced high/low using stan-
dard JTAG instructions. The MAX16031/MAX16032 con-
tain extra JTAG instructions and registers not included in
the JTAG specification that provide access to internal
memory. The extra instructions are: LOAD ADDRESS,
WRITE, READ, REBOOT, SAVE, and USERCODE. The
extra registers are: memory address, memory write,
memory read, and user-code data. See Figure 6 for a
Special Commands
The MAX16031/MAX16032 provide software reboot and
fault log commands. A software reboot initiates the
boot-up sequence, which normally occurs at POR.
During boot-up, EEPROM configuration data is copied
to registers. To initiate a software reboot, send 0xFC
using the send byte format. A software-initiated fault log
is functionally the same as a hardware-initiated fault
log. During a fault log, ADC registers and fault informa-
tion are logged in EEPROM. To trigger a software initi-
ated fault log, send 0xFD using the send byte format.

Test Access Port (TAP) Controller State Machine
The TAP controller is a finite state machine that
responds to the logic level at TMS on the rising edge of
TCK. See Figure 7 for a diagram of the finite state
machine.
Test-Logic-Reset: At power-up, the TAP controller is in
the test-logic-reset state. The instruction register con-
tains the IDCODE instruction. All system logic of the
device operates normally.
