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 7-4
bit 3-0
Unimplemented: Read as ‘0’
RA<3:0>: PORTA I/O Value bits (RA3 is read-only)
Note 1: Writes to PORTx are actually written to the corresponding LATx register. Reads from PORTx register
return actual I/O pin values.
