bit 7 bit 0

Legend:

R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’

-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown

bit 7 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

bit 6 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

bit 5 RJPU: PORTJ Pull-up Enable bit

(2)

1 = PORTJ pull-up resistors are enabled by individual port latch values

0 = All PORTJ pull-up resistors are disabled

bit 4-3 Unimplemented: Read as ‘0’

bit 2-1 RTSECSEL<1:0>: RTCC Seconds Clock Output Select bits

(1)

11 = Reserved; do not use

10 = RTCC source clock is selected for the RTCC pin (the pin can be LF-INTOSC or SOSC, depending

on the RTCOSC (CONFIG3L<1>) bit setting)

01 = RTCC seconds clock is selected for the RTCC pin

00 = RTCC alarm pulse is selected for the RTCC pin

bit 0 Unimplemented: Read as ‘0’

Note 1: To enable the actual RTCC output, the RTCOE (RTCCFG<2>) bit must be set.

2: Unimplemented on 64-pin devices (PIC18F6XK22), read as ‘0’.
