Legend:
R = Readable bit
u = Bit is unchanged
â1â = Bit is set
W = Writable bit
x = Bit is unknown
â0â = Bit is cleared
U = Unimplemented bit, read as â0â
-n/n = Value at POR and BOR/Value at all other Resets
bit 7-6
bit 5-0
Unimplemented: Read as â0â
RA<5:0>: PORTA I/O Value bits(1)
1 = Port pin is > VIH
0 = Port pin is < VIL
Note 1: Writes to PORTA are actually written to corresponding LATA register. Reads from PORTA register is return
of actual I/O pin values.

1 = PORTA pin configured as an input (tri-stated)
0 = PORTA pin configured as an output
Note 1: Unimplemented, read as â1â.
