PORTx

PORTx Register

Important:

Writes to PORTx are actually written to the corresponding LATx register. Reads from PORTx register return actual I/O pin values.
The PORT bit associated with the MCLR pin is read-only and will read ‘1’ when the MCLR function is enabled (LVP = 1 or (LVP = 0 and MCLRE = 1))
Refer to the “Pin Allocation Table” for details about MCLR pin and pin availability per port
Unimplemented bits will read back as ‘0’

Port I/O Value

Value	Description
1	PORT pin is ≥ V_IH
0	PORT pin is ≤ V_IL

Bits 0, 1, 2, 3, 4, 5, 6, 7 – Rxn: Port I/O Value
