REJ10J1459-0200 Rev.2.00 Sep 16, 2006
3. Executing the self-check
4. Using or not using the address match break function
5. Using or not using the CPU rewrite mode
Using or not using the address match break
function
Specify whether or not to use the address match break
function.
- To use the address match break function (default), select
the check box (marked by a check mark when selected).
In this case, the address match interrupt is used by the
emulator, and cannot be used in the user program.
- When not using the address match break function,
deselect the check box (check mark cleared). In this case,
the address match interrupt can be used in the user
program.
This option can be selected or deselected only when you are
starting up the emulator debugger.
Using or not using the CPU rewrite mode
Specify whether or not to debug in CPU rewrite mode. To
debug the user system that uses CPU rewrite mode, select
the check box. This option can be selected or deselected
only when you are starting up the emulator debugger.
Note:
When debugging in CPU rewrite mode is enabled, the
following functions cannot be used while executing the user
program:
- Software breakpoint setting in the internal ROM area
- Execution of COME in the internal ROM area
Executing the self-check
Enable this function when you want the emulator to be self-
checked at startup. Be sure to select the check box only
when you want the emulator to be self-checked at startup.
This function may be enabled in the following cases:
- When you are using the emulator you have just
purchased
- When you successfully download the firmware, but fail
to start up the emulator
- When you want to confirm whether the emulator is
operating normally because, for example, the MCU runs
out of control or something is wrong with the trace
results
This function can be enabled only when you are starting up
the emulator debugger.
