CHAPTER 2 DEPENDENCE FUNCTIONS

2.6.6

To Interrupt the Program Execution [Break]

This section describes the method of interrupting the execution of the user program in
the MB2100-01 emulator debugger.

■

Break Functions

The function to interrupt the execution of the user program is called a break function.

This Emulator debugger provides the following seven types of break functions;

•

Code break (hardware)

•

Code break (hardware/count)

•

Code break (software)

•

Data break

•

Forced break

•

Data watch break

•

Sequencer

When by each break function aborts program execution, the address where a break occurred and the break

factor are displayed.
