Supported Commands Transaction Type
A direct communication to the BCM internal µC 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.

Page Command (00h)
The page command data byte of 00h prior to a command call will
address the internal µC specific data and a page data byte of FFh
would broadcast to all of the connected BCMs. The value of the
Data Byte corresponds to the pin name trailing number with the
exception of 00h and FFh.

Description
OPERATION Command (01h)
The Operation command can be used to turn on and off the
connected BCM. Note that the host OPERATION command will not
enable the BCM if the BCM EN pin is disabled in hardware with
respect to the pre‐set pin polarity. Only with the EN pin active, will
the OPERATION command provide ON/OFF control.
If synchronous startup is required in the system, it is recommended
to use the command from host PMBus in order to achieve
simultaneous array startup.
Unit is On when asserted (default)

This command accepts only two data values: 00h and 80h. If any
other value is sent the command will be rejected and a CML Data
error will result.
