Port J general purpose input/output data—Data Register, pin interrupt input/output
The associated pin can be used as general purpose I/O. In general purpose output mode the register bit value is
driven to the pin.
If the associated data direction bit is set to 1, a read returns the value of the port register bit, otherwise the buffered
pin input state is read.
• Pin interrupts can be generated if enabled in input or output mode.
