Table 4. PAGE Commands
PMBus Commands
A summary of the PMBus commands supported by the device is described in the following sections.
PAGE (00h)
The device can monitor up to four remote voltages or currents: up to two remote diode temperature sensors, and
an internal temperature sensor using one PMBus (I
2
C) address. Send the PAGE command with data 0 to 6 to
select which voltage or current or temperature sensor is affected by all the following PMBus commands. 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 PMBus commands in Table 1 should apply to all pages at the same time.
