Delay Function
If a delay is configured either on or off, the input must
be continuously static through the delay time before the
outputchangesstate.SeetheFigure9.
MFR_VOUT_PEAK (D4h)
TheMFR_VOUT_PEAKcommandreturnsthemaximum
actualmeasuredoutputvoltage.Toresetthisvalueto0,
writetothiscommandwithadatavalueof0.Anyvalues
written to this command are used as a comparison for
future peak updates. The 2 data bytes are in DIRECT
format.
MFR_IOUT_PEAK (D5h)
TheMFR_IOUT_PEAKcommandreturnsthemaximum
actualmeasuredcurrent.Toresetthisvalueto0,writeto
thiscommandwithadatavalueof0.Anyvalueswrittento
this command are used as a comparison for future peak
updates.The2databytesareinDIRECTformat.
MFR_TEMPERATURE_PEAK (D6h)
TheMFR_TEMPERATURE_PEAKcommandreturnsthe
maximum measured temperature. To reset this value to
its lowest value, write to this command with a data value
of8000h.Anyothervalueswrittenbythiscommandare
used as a comparison for future peak updates. The 2 data
bytesareinDIRECTformat.
MFR_VOUT_MIN (D7h)
The MFR_VOUT_MIN command returns the minimum
actual measured output voltage. To reset this value, write to
thiscommandwithadatavalueof7FFFh.Anyvalueswrit-
ten to this command are used as a comparison for future
minimumupdates.The2databytesareinDIRECTformat.
MFR_IOUT_AVG (E2h)
The MFR_IOUT_AVG command returns the calculated
average current. The number of samples collected in the
average before reporting the value in MFR_IOUT_AVG
isconfiguredusingthe IOUT_AVGbitsin MFR_MODE.
Writestothiscommandareignored.The2databytesare
inDIRECTformat.
MFR_NV_LOG_CONFIG (D8h)
TheMFR_NV_LOG_CONFIGcommandisusedtocon-
figure the operation of the nonvolatile fault logging in
the device. The MFR_NV_LOG_CONFIG command is
describedinTable28.
