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.
To enable the actual RTCC output, the RTCOE (RCFGCAL<10>) bit must also be set.
CAL<7:0>: RTC Drift Calibration bits
01111111 = Maximum positive adjustment; adds 508 RTC clock pulses every one minute
.
.
.
11111111 = Minimum negative adjustment; subtracts 4 RTC clock pulses every one minute
00000001 = Minimum positive adjustment; adds 4 RTC clock pulses every one minute
00000000 = No adjustment
.
.
.
10000000 = Maximum negative adjustment; subtracts 512 RTC clock pulses every one minute
Unimplemented: Read as ‘0’
RTSECSEL: RTCC Seconds Clock Output Select bit
1 = RTCC seconds clock is selected for the RTCC pin
0 = RTCC alarm pulse is selected for the RTCC pin
PMPTTL: EPMP Module TTL Input Buffer Select bit
1 = EPMP module inputs (PMDx, PMCS1) use TTL input buffers
0 = EPMP module inputs use Schmitt Trigger input buffers
