The serial peripheral interface (SPI) provides synchronous
communication between the MCU and peripheral devices such as
transistor-transistor logic (TTL) shift registers, liquid crystal display
(LCD) drivers, analog-to-digital (A/D) converter subsystems, and other
processors. Synchronous communication requires a clock and, in the
M68HC11 series, a slave-select signal, but provides substantially faster
communication than the asynchronous SCI, which does not require this
