1: The clock is enabled.
0: The clock is disabled.
Selects prescaler bit PSEL as source clock for the RTC.
This bit is set when the RTC is busy and will discard writes to TOP, VAL, and CTRL.
This bit is cleared when the RTC accepts writes to TOP, VAL, and CTRL.
1: The RTC uses the 32 KHz oscillator as clock source.
0: The RTC uses the RC oscillator as clock source.
1: The RTC wakes up the CPU from sleep modes.
0: The RTC does not wake up the CPU from sleep modes.
Writing a one to this bit clears the prescaler.
Writing a zero to this bit has no effect.
This bit always reads as zero.
1: The RTC is enabled.
0: The RTC is disabled.
