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 5-3
bit 2
bit 1-0
Unimplemented: Read as ‘0’
RA<5:3>: PORTA I/O Value bits⁽¹⁾
1 = Port pin is > VIH
0 = Port pin is < VIL
Unimplemented: Read as ‘0’
RA<1:0>: 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.
