9.6.
After waking from ULP Mode, the ULPST register may be used to determine the cause of wake up. The three pos-
sible wake up sources are SmaRTClock Alarm, SmaRTClock Oscillator Failure, and ULP Port Match. If none of the
bits in ULPST are set, then the wake up was due to the NSS or PWR pin falling edge.
This register may be cleared by writing a 1 to the CLEAR (MSCN.6) bit in the master control register.
