bit 7-0
WPUB – WEAK PULL-UP REGISTER (ADDRESS: 95h)
bit 7
WPUB<7:0>: Weak Pull-up Register bits
1 = Pull-up enabled
0 = Pull-up disabled
Legend:
R = Readable bit
- n = Value at POR

R/W-1
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
(TRISB<7:0> = 0).
