BCM4414xG0F4440yzz
Supported Commands Transaction Type
Page Command (00h)
A direct communication to the BCM controller and a simulated
communication to non-PMBus™ devices is enabled by a page
command. Supported command access privileges with a
pre-selected PAGE are defined in the following table. Deviation
from this table generates a communication error in
STATUS_CML register.
The page command data byte of 00h prior to a command call will
address the BCM controller specific data and a page data byte
of 01h would broadcast to the BCM. The value of the Data Byte
corresponds to the pin name trailing number with the exception
of 00h and FFh.

If synchronous start up is required in the system, it is recommended
to use the command from host PMBus in order to achieve
simultaneous array start up.
