ALE—Alarm Interrupt Enable
This bit allows the real-time clock to generate an interrupt when the ALR bit is set.
RTF—Real-Time Clock Freeze Enable
RTE—Real-Time Clock Enable
12.7.2 Real-Time Clock Register
The 32-bit real-time clock (RTC) register contains the current value of the real-time clock.
The maximum value is approximately 136 years.
