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 4-0
Unimplemented: Read as ‘0’
WPUA5: Weak Pull-up RA5 Control bit
If MCLRE in Configuration Word 1 = 0, MCLR is disabled):
1 = Weak Pull-up enabled(1)
0 = Weak Pull-up disabled
If MCLRE in Configuration Word 1 = 1, MCLR is enabled):
Weak Pull-up is always enabled.
Unimplemented: Read as ‘0’
Note 1: Global WPUEN 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.

ANSA<4:0>: Analog Select between Analog or Digital Function on pins RA<4:0>, respectively
0 = Digital I/O. Pin is assigned to port or digital special function.
1 = Analog input. Pin is assigned as analog input(1). Digital input buffer disabled.
Note 1: When setting a pin to an analog input, the corresponding TRIS bit must be set to Input mode in order to
allow external control of the voltage on the pin.
