PMBus COMMAND DETAILS
STATUS_MFR_SPECIFIC
The STATUS_MFR_SPECIFIC commands returns one byte with the manufacturer specific status information.
Each channel has a copy of the same information. Only bit 0 is page specific.
The format for this byte is:
BIT MEANING
7
Internal Temperature Fault Limit Exceeded.
6
Internal Temperature Warn Limit Exceeded.
5
Factory Trim Area NVM CRC Fault.
4
PLL is Unlocked
3
Fault Log Present
2
VDD33 UV or OV Fault
0
GPIO Pin Asserted Low by External Device (paged)
If any of these bits are set, the MFR bit in the STATUS_WORD will be set.
The user is permitted to write a 1 to any bit in this command to clear a specific fault. This permits the user to clear
status by means other than using the CLEAR_FAULTS command. Exception: The fault log present bit can only be cleared
by issuing the MFR_FAULT_LOG_CLEAR command.
Any supported fault bit in this command will initiate an ALERT event.
This command has one data byte.
MFR_PADS
This command provides the user a means of directly reading the digital status of the I/O pins of the device. The bit
assignments of this command are as follows:
BIT ASSIGNED DIGITAL PIN
15
VDD33 OV Fault
14
VDD33 UV Fault
13
Reserved
12
Reserved
11
ADC Values Invalid, Occurs
During Start-Up
10
Device Driving ALERT Low
9
PowerGood1
8
PowerGood0
7
Device Driving RUN1 Low
6
Device Driving RUN0 Low
5
RUN1
4
RUN0
3
Device Driving GPIO1 Low
2
Device Driving GPIO0 Low
1
GPIO1
0
GPIO0
A 1 indicates the condition is true.
This read-only command has two data bytes.
