Power-Up Default Value:
Command_Byte Value (R/W):
0000 0000b = 00h
0000 0011b = 03h
The power-up default value is 00h. Slot is disabled upon power-up, i.e., all supply outputs are off.
Notes:
1.
The state of the /PWRGDB pin is the logical AND of the values of the AUXBPG and the MAINBPG bits, except when /FORCE_ONB is asserted. If
/FORCE_ONB is asserted (the pin is pulled low), and /FORCE_BENABLE is set to a logic zero, the /PWRGDB pin will be unconditionally forced to
its open-drain (“Power Not Good”) state.
