The brownout detector provides the bodcore_in signal to the SUPC which indicates that the volt-
age regulation is operating as programmed. If this signal is lost for longer than 1 slow clock
period while the voltage regulator is enabled, the Supply Controller can assert vddcore_nreset.
This feature is enabled by writing the bit, BODRSTEN (Brownout Detector Reset Enable) to 1 in
the Supply Controller Mode Register (SUPC_MR).
If BODRSTEN is set and the voltage regulation is lost (output voltage of the regulator too low),
the vddcore_nreset signal is asserted for a minimum of 1 slow clock cycle and then released if
bodcore_in has been reactivated. The BODRSTS bit is set in the Supply Controller Status Reg-
ister (SUPC_SR) so that the user can know the source of the last reset.
Until bodcore_in is deactivated, the vddcore_nreset signal remains active.
The wake up events allow the device to exit backup mode. When a wake up event is detected,
the Supply Controller performs a sequence which automatically reenables the core power
supply.
