Description
Calibration direction
Forward calibration. When CALVAL is equal to the
calibration counter, the RTC timers will jump by 2 seconds.
Backward calibration. When CALVAL is equal to the
calibration counter, the RTC timers will stop incrementing for
1 second.
Reserved, user software should not write ones to reserved
bits. The value read from a reserved bit is not defined.
