DESCRIPTION The OUT instruction writes a 16-bit value from a data memory
                                                    __
            location to the specified I/O port. The IS line goes low to
                                            ____    _
            indicate an I/O access, and the STRB, R/W, and READY are the
            same as for an external data memory write. OUT is a single
            cycle instruction when in the PI/DI memory configuration.
