23.4.9.3 Clock Alarms
The RTC and the RTT alarms can generate a wakeup of the core power supply. This can be enabled by setting, respectively, SUPC_WUMR.RTCEN and SUPC_WUMR.RTTEN.
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.
