Chapter 20
Background Debug Mode (BDM) Interface
This chapter details the MCF5253 hardware debug support. The topics discussed are real-time trace
support, background debug mode (BDM), and real-time debug support. The memory map, register
descriptions and debug support operation are provided.
The MCF5253 implements an enhanced debug architecture. The original design plus these enhancements
is known as Revision A (or Rev. A). The enhanced functionality is clearly identified in this chapter. The
Rev. A enhancements are backward compatible with the original ColdFire debug definition.
The general topic of debug support is divided into three separate areas:
The logic required to support these three areas is contained in a debug module as shown in
20.1
This section describes signals associated with the debug module. All ColdFire debug signals are
unidirectional and are related to the rising-edge of the processor core’s clock signal.
