To enable the actual RTCC output, the RTCOE (RTCCFG<2>) bit must be set.
Unimplemented on 64-pin devices (PIC18F6XK22), read as ‘0’.
RDPU: PORTD Pull-up Enable bit
1 = PORTD pull-up resistors are enabled by individual port latch values
0 = All PORTD pull-up resistors are disabled
REPU: PORTE Pull-up Enable bit
1 = PORTE pull-up resistors are enabled by individual port latch values
0 = All PORTE pull-up resistors are disabled
RJPU: PORTJ Pull-up Enable bit
1 = PORTJ pull-up resistors are enabled by individual port latch values
0 = All PORTJ pull-up resistors are disabled
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 LF-INTOSC or SOSC, depending on
01 = RTCC seconds clock is selected for the RTCC pin
00 = RTCC alarm pulse is selected for the RTCC pin
Unimplemented: Read as ‘0’
