For more information 

MFR_FAULT_LOG_CLEAR
This command initializes the EEPROM block reserved for fault logging. Any previous fault log stored in EEPROM will 

be erased by this operation and logging of the fault log RAM to EEPROM will be enabled.

MFR_FAULT_LOG_STATUS
Read only. This register is used to manage fault log events.
Mfr_fault_log_status_eeprom is set after a MFR_FAULT_LOG_STORE command or a faulted-off event triggers a transfer 

of the fault log from RAM to EEPROM. This bit is cleared by a MFR_FAULT_LOG_CLEAR command.
Mfr_fault_log_status_ram is set after a MFR_FAULT_LOG_RESTORE to indicate that the data in the RAM has been 

restored from EEPROM and not yet read using a MFR_FAULT_LOG command. This bit is cleared by a successful 

execution of an MFR_FAULT_LOG command, or by a successful execution of an MFR_FAULT_LOG_CLEAR command.

b[1] Mfr_fault_log_status_ram

Fault log RAM status:
0: The fault log RAM allows updates.
1: The fault log RAM is locked until the next MFR_FAULT_LOG read.

b[0] Mfr_fault_log_status_eeprom Fault log EEPROM status:

0: The transfer of the fault log RAM to the EEPROM is enabled.
1: The transfer of the fault log RAM to the EEPROM is inhibited.
