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

: 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.
