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 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.
