(3) Setting break points 
 
1. Screen after software breakpoint setup 

 

Breakpoint setup screen 

There are three types of breakpoints as described 
below. 
- Address 

match 

breakpoint 

  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 address match breakpoint display 
area in the editor (source) window. (A blue circle 
is displayed at the setting line) 

  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 

  A software breakpoint can be set or cleared by 

double-clicking the software breakpoint display 
area in the editor (source) window (A red circle is 
displayed at the setting line). 
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 

  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).
