5.6 DEVELOPMENT SUPPORT
All M68000 family members have the following special features that facilitate applications
development.
Trace on Instruction Execution—All M68000 processors include an instruction-by-instruc-
tion tracing facility to aid in program development. The MC68020, MC68030, and CPU32+
can also trace those instructions that change program flow. In trace mode, an exception is
generated after each instruction is executed, allowing a debugger program to monitor exe-
cution of a program under test. See 5.5.2.10 Tracing for more information.
Breakpoint Instruction—An emulator can insert software breakpoints into target code to indi-
cate when a breakpoint occurs. On the MC68010, MC68020, MC68030, and CPU32+, this
function is provided via illegal instructions ($4848–$484F) that serve as breakpoint instruc-
tions. See 5.5.2.5 Software Breakpoints for more information.
Unimplemented Instruction Emulation—When an attempt is made to execute an illegal
instruction, an illegal instruction exception occurs. Unimplemented instructions (F-line, A-
line) utilize separate exception vectors to permit efficient emulation of unimplemented
instructions in software. See 5.5.2.8 Illegal or Unimplemented Instructions for more informa-
tion.
5.6.1 CPU32+ Integrated Development Support
In addition to standard MC68000 family capabilities, the CPU32+ has features to support
advanced integrated system development. These features include background debug
mode, deterministic opcode tracking, hardware breakpoints, and internal visibility in a sin-
gle-chip environment.
5.6.1.1 BACKGROUND DEBUG MODE (BDM) OVERVIEW. Microprocessor
generally provide a debugger, implemented in software, for system analysis at the lowest
level. The BDM on the CPU32+ is unique because the debugger is implemented in CPU
microcode.
BDM incorporates a full set of debug options—registers can be viewed and/or altered, mem-
ory can be read or written, and test features can be invoked.
A resident debugger simplifies implementation of an in-circuit emulator. In a common setup
(see Figure 5-18), emulator hardware replaces the target system processor. A complex,
expensive pod-and-cable interface provides a communication path between target system
and emulator.
