SECTION 20
DEVELOPMENT CAPABILITIES AND INTERFACE
This section discusses the on-chip features that are used during the development phase.
Background debug monitors and emulators are used to interface with this MPC823
capability. Emulators require a level of control and observation that are in sharp contrast to
the trend of modern microcomputers and microprocessors in which many bus cycles are
directed to internal resources and are not externally visible. The same is true for bus
analyzers. To enhance support for development tools, some of the development support
functions are implemented in the silicon. Program flow tracking, watchpoint and breakpoint
generation, and emulation systems that control core activity are just some of the features
that allow you to efficiently debug systems based on the MPC823.
