(3) Setting breakpoints
1. Screen after breakpoint setup
Breakpoint setup screen
There are three types of breakpoints as described below.
- Address match breakpoint (A)
This breakpoint can be set only when you chose to use
the address match break function on the MCU tab of the
Init dialog box.
A breakpoint can be set or cleared by double-clicking in
the breakpoint display area.
Up to eight breakpoints can be set. When this limit is
exceeded, software breakpoints are set.
The address match break causes the program to stop
before executing the address at which a breakpoint is set.
- Software breakpoint (B)
A software breakpoint can be set or cleared by double-
clicking the breakpoint display area.
This is rewritten to a break instruction, therefore, because
of rewriting flash ROM, program execution starts with a
delay of several seconds after setting ROM area.
If the breakpoint you set is a software breakpoint, the
program stops before executing the instruction at the set
breakpoint.
- Hardware breakpoint (H)
A hardware breakpoint can be set or cleared by right-
clicking the breakpoint display area.
If the breakpoint you set is a hardware breakpoint, the
program stops after executing the instruction at the set
breakpoint (after several cycles).
