bit 7-0

CAL<7:0>: RTC Drift Calibration bits

01111111 =Maximum positive adjustment; adds 508 RTC clock pulses every one minute

•

•

00000001 =Minimum positive adjustment; adds 4 RTC clock pulses every one minute

00000000 =No adjustment

11111111 =Minimum negative adjustment; subtracts 4 RTC clock pulses every one minute

•

10000000 =Maximum negative adjustment; subtracts 512 RTC clock pulses every one minute

Note 1: The RCFGCAL register is only affected by a POR.

2: A write to the RTCEN bit is only allowed when RTCWREN = 1.

3: This bit is read-only. It is cleared to ‘0’ on a write to the lower half of the MINSEC register.
