CALDIR | Calibration direction 0 (FORWARD_CALIBRATION_): Forward calibration. When CALVAL is equal to the calibration counter, the RTC timers will jump by 2 seconds. 1 (BACKWARD_CALIBRATION): Backward calibration. When CALVAL is equal to the calibration counter, the RTC timers will stop incrementing for 1 second. |
