Command Descriptions
PMBusTM Command set:
Operation (0x01) : By default the Power supply is turned ON
at power up as long as Power ON/OFF signal pin is active HI.
The Operation command is used to turn the Power Supply ON
or OFF via the PMBus. The data byte below follows the
OPERATION command.
Non-supported commands are annunciated.

To RESET the power supply cycle the power supply OFF, wait
at least 2 seconds, and then turn back ON. All alarms and
shutdowns are cleared during a restart.
Clear_faults (0x03): This command clears all STATUS and
FAULT registers and resets the SMBAlert# line.
If a fault still persists after the issuance of the clear_faults
command the specific registers indicating the fault are reset
and the SMBAlert# line is activated again.

WRITE_PROTECT register (0x10): Used to control writing to
the PMBus device. The intent of this command is to provide
protection against accidental changes. All supported
command parameters may have their parameters read,
regardless of the write_protect settings. The default setting of
this register is disable_all_writes except write_protect 0x80h.
