20.3.2 Alarm
Alarm functionality is provided by the Match Value Register, the interrupt generation
logic asserts the interrupt (if enabled) when the Counter reaches this Match Value.
The RTC allows the user to disable interrupt generation and also to mask a generated
interrupt.
Additionally the RTC supports generation of an interrupt when only the RTC clock is
running, this allows the interrupt to be generated when in the Deep Sleep state.
20.3.3 Wake Event
The RTC supports waking the SoC from Low Power States, including Sleep.
The SoC use the RTC interrupt as the source of this wake event so interrupt
generation must be enabled to facilitate this RTC wake capability.
