Port J input data—
A read always returns the buffered input state of the associated pin. It can be used to detect overload or short circuit
conditions on output pins.
Port J data direction—
This bit determines whether the associated pin is an input or output.
1 Associated pin is configured as output
0 Associated pin is configured as input
