C)
address. Send the PAGE command with data 0 to 11 to select which power supply or which temperature sensor or
fan is affected by all the PMBus commands shown in Table 1. Not all commands are supported within each page. If
an unsupported command is received, the CML status bit is set. Some commands are common, meaning that any
selected page has the same effect on and the same response from the device.
Set the PAGE to 255 when it is desired that the following PMBus commands should apply to all pages at the same time.
There are only a few commands (OPERATION, CLEAR_FAULTS) where this function has a real application.
