User Interface
0: The clock is disabled
1: The clockis enabled
Selects prescaler bit PSEL as source clock for the RTC.
0: The RTC accepts writes to TOP, VAL, and CTRL.
1: The RTC is busy and will discard writes to TOP, VAL, and CTRL.
0: The RTC uses the RC oscillator as clock source
1: The RTC uses the 32 KHz oscillator as clock source
