W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘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
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.
