loaded upon power-on reset or when the RST pin is asserted and the value shown in the Default_Value column is the
value when shipped from the factory. “FIXED” in the Flash_Stored column means this value is fixed at the factory and
cannot be changed.

Note_6:_
The factory-set default value for this 8-byte block is 3130313031303130h.
The factory-set default value for the complete block of the MFR_NV_FAULT_LOG is FFh.
The power-on reset value for this 4-byte block is 00000000h.
The factory-set default value for the complete block of the MFR_FAN_LUT is 00h.

On device power-up, the device samples the A0 and A1
pins to determine the PMBus/SMBus serial-port address.

SMBus/PMBus Operation
The device implements the PMBus command structure
using the SMBus format. The structure of the data flow
between the host and the slave is shown below for sev-
eral different types of transactions. All transactions begin
with a host sending a command code that is immediately
preceded with a 7-bit slave address (R/ W = 0). Data is
sent most significant bit (MSB) first.
