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 7-0
Rx<7:0>: Rx7:Rx0 Port I/O Value bits
1 = Port pin is  VIH
0 = Port pin is  VIL
Note 1: Writes to PORTx are actually written to the corresponding LATx register.
Reads from PORTx register return actual I/O pin values.

Note 1: Bits RB6 and RB7 read ‘1’ while in Debug mode.
2: Bit PORTE3 is read-only, and will read ‘1’ when MCLRE = 1 (Master Clear enabled).
