Legend:
R = Readable bit
W = Writable bit
‘1’ = Bit is set
‘0’ = Bit is cleared
-n/n = Value at POR and BOR/Value at all other Resets
U = Unimplemented bit, read as ‘0’
x = Bit is unknown
bit 7-4

Port is available as input only when MCLRE = 0.
Writes to PORTx are written to corresponding LATx register. Reads from PORTx register is return of I/O
pin values.
Available on PIC18(L)F4XK22 devices.
