Using the Serial Peripheral Interface to Communicate Between Multiple Microcomputers
Application Notespdf934 11/28/2002
AN991 - As the complexity of user applications increases, many designers find themselves needing multiple microprocessors to provide necessary functionality in a circuit. Communication between multiple processors can often be difficult, especially when differing processors are used. A possible solution to this problem is usage of the serial peripheral interface (SPI), and interface intended for communication between integrated circuits on the same printed wire board. The MC68HC05C4 is one of the first single-chip microcomputers to incorporate SPI into hardware. (Scanned legacy document -- may take a  few minutes to download.)
