R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown

bit 3
bit 2-0
Unimplemented: Read as ‘0’
WPUA<5:4>: Weak Pull-up Control bits
1 = Pull-up enabled
0 = Pull-up disabled
Unimplemented: Read as ‘0’
WPUA<2:0>: Weak Pull-up Control bits
1 = Pull-up enabled
0 = Pull-up disabled

Global RAPU must be enabled for individual pull-ups to be enabled.
The weak pull-up device is automatically disabled if the pin is in Output mode (TRISA = 0).
The RA3 pull-up is enabled when configured as MCLR and disabled as an input in the Configuration
Word.
WPUA<5:4> always reads ‘1’ in XT, HS and LP Oscillator modes.
