Intended Audience
Part IV is intended for hardware designers who need to know the functions and electrical
characteristics of the MCF5407 interface. It includes a pinout, and both electrical and
functional descriptions of the MCF5407 signals. It also describes how these signals interact
to support the variety of bus operations shown in timing diagrams.
Contents
Part IV contains the following chapters:
• Chapter 16, “Mechanical Data,” provides a functional pin listing and package
• Chapter 17, “Signal Descriptions,” provides an alphabetical listing of MCF5407
• Chapter 18, “Bus Operation,” describes data transfers, error conditions, bus
• Chapter 19, “IEEE 1149.1 Test Access Port (JTAG),” describes configuration and
• Chapter 20, “Electrical Specifications,” describes AC and DC electrical
diagram for the MCF5407.
signals. This chapter describes the MCF5407 signals. In particular, it shows which
are inputs or outputs, how they are multiplexed, which signals require pull-up
resistors, and the state of each signal at reset.
arbitration, and reset operations. It describes transfers initiated by the MCF5407 and
by an external bus master, and includes detailed timing diagrams showing the
interaction of signals in supported bus operations. Note that Chapter 11,
“Synchronous/Asynchronous DRAM Controller Module,” describes DRAM cycles.
operation of the MCF5407 JTAG test implementation. It describes the use of JTAG
instructions and how to disable JTAG functionality.
