CLEAR_FAULTS
Clear any fault bits that may have been set, also releases the SMBALERT#
signal if the device has been asserting it.

WRITE_PROTECT
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

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)
YES
