To enable the actual RTCC output, the RTCOE (RTCCFG<2>) bit must be set.
If the Timer1 oscillator is the clock source for RTCC, the T1OSCEN bit should be set (T1CON<3> = 1).
Unimplemented: Read as ‘0’
RTSECSEL<1:0>: RTCC Seconds Clock Output Select bit
11 = Reserved; do not use
10 = RTCC source clock is selected for the RTCC pin (pin can be INTOSC or Timer1 oscillator, depending
01 = RTCC seconds clock is selected for the RTCC pin
00 = RTCC alarm pulse is selected for the RTCC pin
Unimplemented: Read as ‘0’
CAL<7:0>: RTC Drift Calibration bits
