The serial peripheral interface (SPI) allows several MC68HC05
microcontrollers (MCUs) or an MC68HC05 MCU plus peripheral devices
to be interconnected within a single printed circuit board. In an SPI,
separate wires are required for data and clock. In the SPI format, the
clock is not included in the data stream and must be furnished as a
separate signal.
