To enable the actual RTCC output, the RTCOE (RTCCFG<2>) bit must be set.
Available only in 80-pin parts.
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
Unimplemented: Read as ‘0’
