Unimplemented: Read as ‘0’
CAL<9:0>: RTC Drift Calibration bits
Contains a signed 10-bit integer value.
0111111111= Maximum positive adjustment, adds 511 RTC clock pulses every one minute
...
0000000001= Minimum positive adjustment, adds 1 RTC clock pulse every one minute
0000000000= No adjustment
1111111111= Minimum negative adjustment, subtracts 1 RTC clock pulse every one minute
...
1000000000= Minimum negative adjustment, subtracts 512 clock pulses every one minute
ON: RTCC On bit
1 = RTCC module is enabled
0 = RTCC module is disabled
Note: The ON bit is only writable when RTCWREN = 1.
FRZ: Freeze in Debug Mode bit
1 = When emulator is in Debug mode, module freezes operation
0 = When emulator is in Debug mode, module continues operation
Note: The FRZ bit always reads ‘0’ unless in Debug mode.
SIDL: Stop in Idle Mode bit
1 = Disables the PBCLK to the RTCC when CPU enters in Idle mode
0 = Continue normal operation in Idle mode
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
Note: Requires RTCOE == 1 (RTCCON<0>) for the output to be active.
RTCCLKON: Status of the RTCC Clock Enable bit
1 = RTCC clock is actively running
0 = RTCC clock is not running
