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

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.
