This chapter describes the MCF5307 I
synchronization, and the registers in the I
programming examples.
8.1 Overview
I
exchange, minimizing the interconnection between devices. This bus is suitable for
applications requiring occasional communications over a short distance between many
devices. The flexible I

This feature supports complex applications with multiprocessor control and can be used for
rapid testing and alignment of end products through external connections to an
assembly-line computer.
