16.4.7.2 Clock Alarms
The RTC and the RTT alarms can generate a wake up of the core power supply. This can be
enabled by writing respectively, the bits RTCEN and RTTEN to 1 in the Supply Controller Wake
Up Mode Register (SUPC_WUMR).
The Supply Controller does not provide any status as the information is available in the User
Interface of either the Real Time Timer or the Real Time Clock.
16.4.7.3 Supply Monitor Detection
The supply monitor can generate a wakeup of the core power supply. See Section 16.4.4 ”Sup-
