Intended Audience

Part III describes the operation and conﬁguration of the MCF5407 DMA, timer, UART, and

parallel port modules, and describes how they interface with the system integration unit,

described in Part II.

Contents

It contains the following chapters:

— Chapter 12, “DMA Controller Module,” provides an overview of the DMA

controller module and describes in detail its signals and registers. The latter

sections of this chapter describe operations, features, and supported data transfer

modes in detail, showing timing diagrams for various operations.

— Chapter 13, “Timer Module,” describes conﬁguration and operation of the two

general-purpose timer modules, timer 0 and timer 1. It includes programming

examples.

— Chapter 14, “UART Modules,” describes the use of the universal

asynchronous/synchronous receiver/transmitters (UARTs) implemented on the

MCF5407 and includes programming examples. Particular attention is given to

the UART1 implementation of a synchronous interface that provides a controller

for an 8- or 16-bit CODEC interface and an audio CODEC ‘97 (AC ’97) digital

interface.

— Chapter 15, “Parallel Port (General-Purpose I/O),” describes the operation and

programming model of the parallel port pin assignment, direction-control, and

data registers. It includes a code example for setting up the parallel port.
