.
01111111 = Minimum positive adjustment; adds 1 RTC clock pulse every 15 seconds
00000000 = No adjustment
11111111 = Minimum negative adjustment; subtracts 1 RTC clock pulse every 15 seconds

10000000 = Maximum negative adjustment; subtracts 128 RTC clock pulses every 15 seconds
Note 1:

3:
The RCFGCAL register is only affected by a POR.
A write to the RTCEN bit is only allowed when RTCWREN = 1.
This bit is read-only; it is cleared to ‘0’ on a write to the lower half of the MINSEC register.
