Read-write

Allows to select the threshold voltage of the supply monitor. Refer to electrical characteristics for voltage values.

0 (NOT_ENABLE) = the core reset signal “vddcore_nreset” is not affected when a supply monitor detection occurs.

1 (ENABLE) = the core reset signal, vddcore_nreset is asserted when a supply monitor detection occurs.

0 (NOT_ENABLE) = the SUPC interrupt signal is not affected when a supply monitor detection occurs.

1 (ENABLE) = the SUPC interrupt signal is asserted when a supply monitor detection occurs.
