CHAPTER 2  DEPENDENCE FUNCTIONS

2.1.9

Break

In the simulator debugger, five types of break functions can be used. When the program 
execution is aborted by each break function, the address and the break factor to do the 
break are displayed.

■

Break Functions

In this simulator debugger, the following five types of break functions are supported.

•

Code break

•

Data break

•

Trace-buffer-full break

•

Guarded break

•

Forced break
