Manufacturer-Specific PMBusTM Commands
Data out_of_range
Remote ON [logic HI = 1]
Many of the manufacturer-specific commands read back
more than two bytes. If more than two bytes of data are
returned, the standard SMBusTM Block read is utilized. In this
process, the Master issues a Write command followed by the
data transfer from the power supply. The first byte of the
Block Read data field sends back in hex format the number of
data bytes, exclusive of the PEC number, that follows. Analog
data is always transmitted LSB followed by MSB. A No-ack
following the PEC byte signifies that the transmission is
complete and is being terminated by the ‘host’.
Isolation test failed: The ‘system controller’ has to determine
that sufficient capacity exists in the system to take a power
supply ‘off line’ in order to test its isolation capability. Since
the power supply cannot determine whether sufficient
redundancy is available, the results of this test are provided,
but the ‘internal fault’ flag is not set.

Mfr_Specific Status and alarm registers: The content and
partitioning of these registers is significantly different than
the standard register set in the PMBus™ specification. More
information is provided by these registers and they are either
accessed rapidly, at once, using the ‘multi parameter’ read
back scheme of this document, or in batches of two STATUS
and two ALARM registers.
