(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).
