Section 10. Serial Peripiheral Interface (SPI)
10.1 Contents
10.2 Introduction
The serial peripheral interface (SPI) is an interface built into the
MC68HC05 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.
