WPUB5 WPUB4 WPUB3 WPUB2 WPUB1 WPUB0

bit 0

bit 7-6

bit 5-0

Unimplemented: Read as ‘0’

WPUB<5:0>: Weak Pull-up Register bit

1 = Pull-up disabled

0 = Pull-up enabled

Note 1: Global RBPU must be enabled for individual pull-ups to be enabled.

2: The weak pull-up device is automatically disabled if the pin is in output mode

(TRIS = 0).

Legend:

R = Readable bit

- n = Value at POR

W = Writable bit

’1’ = Bit is set

U = Unimplemented bit, read as ‘0’

’0’ = Bit is cleared x = Bit is unknown

Unimplemented: Read as ‘0’

IOCB<5:0>: Interrupt-on-Change PORTB Control bit

1 = Interrupt-on-change enabled

0 = Interrupt-on-change disabled

Note 1: Global interrupt enables (GIE and RBIE) must be enabled for individual interrupts to

be recognized.

Legend:

R = Readable bit

- n = Value at POR

W = Writable bit

’1’ = Bit is set

U = Unimplemented bit, read as ‘0’

’0’ = Bit is cleared x = Bit is unknown
