(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).
