R = Readable bit
u = Bit is unchanged
‘1’ = Bit is set
W = Writable bit
x = Bit is unknown
‘0’ = Bit is cleared
U = Unimplemented bit, read as ‘0’
-n/n = Value at POR and BOR/Value at all other Resets
bit 7-6
bit 5-0
Unimplemented: Read as ‘0’
WPUA<5:0>: Weak Pull-up Register bits⁽³⁾
1 = Pull-up enabled
0 = Pull-up disabled
Note 1:

3:
Global WPUEN bit of the OPTION_REG register must be cleared for individual pull-ups to be enabled.
The weak pull-up device is automatically disabled if the pin is in configured as an output.
For the WPUA3 bit, when MCLRE = 1, weak pull-up is internally enabled, but not reported here.
