Writing this register will place the requested contents
into the output buffer. Contents are immediately
available for USB read. The contents occupy
effectively four bytes. In the case of SPI, contents are
transferred to the serial output buffer, so a second
query to the SERIAL_OUT_BUFFER register is required
to transfer its contents and also to clear the output
buffer.
