CLEAR_FAULTS
Clear any fault bits that may have been set, also releases the SMBALERT#
signal if the device has been asserting it.
Used to control writing to the module via PMBus. Copies the current register
setting in the module whose command code matches the value in the data
byte into non-volatile memory (EEPROM) on the module

WRITE_PROTECT
Bit5: 0 –– Enables all writes as permitted in bit6 or bit7
1 –– Disables all writes except the WRITE_PROTECT, OPERATION
and ON_OFF_CONFIG (bit 6 and bit7 must be 0)
Bit 6: 0 –– Enables all writes as permitted in bit5 or bit7
1 –– Disables all writes except for the WRITE_PROTECT and
OPERATION commands (bit5 and bit7 must be 0)
Bit7: 0 –– Enables all writes as permitted in bit5 or bit6
1 –– Disables all writes except for the WRITE_PROTECT command
(bit5 and bit6 must be 0)

STORE_DEFAULT_ALL
Copies all current register settings in the module into non-volatile memory
(EEPROM) on the module. Takes about 50ms for the command to execute.
12
RESTORE_DEFAULT_ALL
Restores all current register settings in the module from values in the
module non-volatile memory (EEPROM)
Copies the current register setting in the module whose command code
matches the value in the data byte into non-volatile memory (EEPROM) on
the module
