A summary of the PMBus commands supported by the device are described in the following sections.
The device can control up to six power supplies and up to eight temperature sensors using one PMBus (I
Send the PAGE command with data 0 to 13 to select which power supply or which temperature sensor 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.
