10.2 Introduction
The serial peripheral interface (SPI) is an interface built into the
MC68HC05 microcontroller unit (MCU) which allows several
MC68HC05 MCUs or 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.
An SPI system may be configured in a system containing one master
MCU and several slave MCUs or in a system in which an MCU is
capable of being a master or a slave.
