bit 0
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
LATA<7:0>: RA<7:0> 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 7-0
ANSA<7:0>: Analog Select between Analog or Digital Function on pins RA<7:0>, 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.
