MFR_FAULT_LOG_STORE
The MFR_FAULT_LOG_STORE command forces a data log to be written to internal EEPROM as if a fault event had occurred.
This command will generate a CML fault if the Enable Fault Logging bit is cleared in MFR_CONFIG_ALL_LTC3882-1.
This write-only command has no data bytes.
MFR_EE_xxxx
The MFR_EE_xxxx commands facilitate bulk programming of the LTC3882-1 internal EEPROM. Contact the factory for details.
USER_DATA_0x
The USER_DATA_0x commands provide uncommitted EEPROM locations that may be applied as system scratchpad
space. USER_DATA_00 and USER_DATA_01 should not be modified when using the LTpowerPlay GUI. Some contract
manufacturers also reserve use of USER_DATA_02 for their own inventory control.
