Breakpoint setup screen
There are two types of breakpoints as described
below.
Either type of breakpoint needs to be used
depending on break mode.
Break modes are switched over by the break mode
select button. The current break mode is shown in
the break mode display area.
BM: S/W Software break mode
BM: H/W Hardware break mode
- Software breakpoint
A software breakpoint can be set or cleared by
double-clicking the breakpoint display area. If
the breakpoint you set is a software breakpoint,
the program stops after executing the instruction
at the set breakpoint.
Up to eight software breakpoints can be used in
a program.
- Hardware breakpoint
For hardware breakpoints, you can select break
conditions in the hardware breakpoint setup
window.
Up to two hardware breakpoints can be used in
a program. The break conditions set can include
an address range or an external trigger as the
cause of break.
