Legend:
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 7-0
WPUA<7:0>: Weak Pull-up Register bits⁽²⁾
1 = Pull-up enabled
0 = Pull-up disabled
Note 1: If MCLRE = 1, the weak pull-up in RA3 is always enabled; bit WPUA3 is not affected.
2: The weak pull-up device is automatically disabled if the pin is configured as an output.

ODCA<7:0>: PORTA Open-Drain Enable bits
For RA<7:0> pins, respectively
1 = Port pin operates as open-drain drive (sink current only)
0 = Port pin operates as standard push-pull drive (source and sink current)
