bit 7
bit 0
Legend:
R = Readable bit
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
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
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’.
