CMD Address	10h
Write Transaction:	Write Byte
Read Transaction:	Read Byte
Format:	Unsigned Binary (1 byte)
Phased:	No

The WRITE_PROTECT command controls writing to the PMBus device. The intent of this command is to provide protection against accidental changes; it has one data byte that is described below. This command does NOT provide protection against deliberate or malicious changes to a configuration or operation of the device. All supported commands can have their parameters read, regardless of the WRITE_PROTECT settings.
