CLEAR_FAULTS is a standard PMBus® command that resets all latched warning/fault/status flags and de-asserts the SMBA# signal. If a fault or warning condition still exists when the CLEAR_FAULTS command is executed, the SMBA# signal may re-assert almost immediately or may not de-assert at all. Issuing the CLEAR_FAULTS command alone will not cause the eFuse to switch back ON in the event of a turn-off due to any fault. That must be done by issuing an OPERATION OFF command followed by OPERATION ON command or a POWER_CYCLE command after the fault condition is cleared, or through an auto-retry sequence. This command also clears the BB_RAM contents and resets the BB_TIMER register to zero (0). This command has no effect on Blackbox EEPROM memory contents.

This command uses the PMBus® send byte protocol. There is no data byte for this command. This command is write only.
