Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
u = Bit is unchanged
x = Bit is unknown
-n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set
‘0’ = Bit is cleared
bit 7-6
Unimplemented: Read as ‘0’
bit 5-4
LATA<5:4>: RA<5:4> Output Latch Value bits(1)
bit 3
Unimplemented: Read as ‘0’
bit 2-0
LATA<2:0>: RA<2:0> Output Latch Value bits(1)
Note 1:
Writes to PORTA are actually written to corresponding LATA register. Reads from PORTA register is return
of actual I/O pin values.

bit 4
ANSA4: Analog Select between Analog or Digital Function on pins RA4, respectively
1 = Analog input. Pin is assigned as analog input(1). Digital input buffer disabled.
0 = Digital I/O. Pin is assigned to port or digital special function.
bit 3
Unimplemented: Read as ‘0’
bit 2-0
ANSA<2:0>: Analog Select between Analog or Digital Function on pins RA<2:0>, respectively
1 = Analog input. Pin is assigned as analog input(1). Digital input buffer disabled.
0 = Digital I/O. Pin is assigned to port or digital special function.
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.
