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 7-0
WPUB<7:0>: Weak Pull-up Register bit
1 = Pull-up enabled
0 = Pull-up disabled
1 = Pull-up enabled
0 = Pull-up disabled
Note 1: Global RBPU bit of the OPTION register must be cleared for individual pull-ups to be enabled.
2: The weak pull-up device is automatically disabled if the pin is in configured as an output.
