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 7-6
bit 5-4
bit 3
bit 2-0
Unimplemented: Read as ‘0
LATA<5:4>: RA<5:4> Output Latch Value bits(1)
Unimplemented: Read as ‘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 2-0
Unimplemented: Read as ‘0’
ANSA4: Analog Select between Analog or Digital Function on pins RA4, 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.
Unimplemented: Read as ‘0’
ANSA<2:0>: Analog Select between Analog or Digital Function on pins RA<2:0>, 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.
