PURPOSE
Not Used
Sets the default to either operate any time
power is present or for the on/off to be
controlled by ENABLE pin, OPERATION
command, or when both the Enable pin and
OPERATION command are valid.

MEANING
Not Used
Device starts any time power is present regardless of ENABLE pin or
OPERATION command states.
Device starts from ENABLE pin only.
Device starts from OPERATION command only.
Device starts when the ENABLE pin is active and OPERATION “on”
command has been sent.
Active low (Pull pin low to start the device)
Active high (Pull pin high to start the device)
Use the programmed ramp down settings
Turn off the output immediately
CLEAR_FAULTS (03h)
Definition: Clears all fault bits in all registers and releases the SALRT pin (if asserted) simultaneously. If a fault condition still exists, the
bit will reassert immediately. This command will not restart a device if it has shut down, it will only clear the faults.

STORE_DEFAULT_ALL (11h)
Definition: Stores all current PMBus™ values from the operating memory into the nonvolatile DEFAULT Store memory. To clear the
DEFAULT store, perform a RESTORE_FACTORY then STORE_DEFAULT_ALL. To add to the DEFAULT store, perform a
RESTORE_DEFAULT_ALL, write commands to be added, then STORE_DEFAULT_ALL. This command should not be used during device
operation, the device will be unresponsive for 20ms while storing values.
