The MFR_NV_LOG_CONFIG command is used to
configure the operation of the nonvolatile fault logging
Table 25. MFR_NV_LOG_CONFIG
*The device clears two fault logs at a time when overwrite is enabled.

for subsequent action. If an error occurs during this action, the device sets the CML
bit in STATUS_WORD; no bits are set in STATUS_CML.
Setting this bit to a 1 forces the

The host must set again for subsequent action. If an error occurs during this action,
the device sets the CML bit in STATUS_WORD; no bits are set in STATUS_CML. While
clearing the fault log, monitoring is stopped and commands should not be sent to the
PMBus port.
These bits always return a 0.
This bit determines the source of the data written into the T0 location of each page
when a nonvolatile fault log is written.
0 = Log the last regular collection interval ADC reading.
1 = Read the latest ADC value before logging.
0 = Do not overwrite the NV fault log.
1 = Overwrite the NV fault log once it is full.*
These bits determine the depth of the NV fault log:
NV_LOG_DEPTH[1:0]
0 = Do not write NV fault log when FAULT is externally pulled low.
1 = Write NV fault log when FAULT is externally pulled low if the FAULT_IGNORE bit in
MFR_MODE is not set.
These bits always return a 0.
