Please kindly advise.

Table 4. Questions about LVD and POR specification.(Document Number MKE04P80M48SF0 Data Sheet: Technical Data Rev. 4, 07/2016)


Since LVDRE of PMC_SPMSC1 is 1 by default, I think that low voltage reset is enabled.
PMC_SPMSC2 defaults to 0.
So, does this low voltage reset take place with VLVDL = 0 or VLVW1L?
               Min Typ Max
VLVDL 2.56 2.61 2.66 V
VLVW1L 2.62 2.7 2.78 V
VLVW2L 2.72 2.8 2.88 V
VLVW3L 2.82 2.9 2.98 V
VLVW4L 2.92 3.0 3.08 V

Or does the low-voltage reset not work unless it is written to PMC_SPMSC2.LVDV?

Hi jun,

   The reset will be take place with VLVDL:

The LVWnL is used to give the warning flag, or trigger the interrupt.

Wish it helps you!

Have a great day,
