Using or not using the address match break function
Because the address match break function cannot be used with this product,
be sure to deselect the box when you start up for the first time.
Using or not using CPU rewrite mode
Specify whether or not to debug in CPU rewrite mode. To debug the user
program 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.
[Supplementary explanation]
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
- Program or data rewrite operation to the internal ROM area
- Hardware break point and trace point settings
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.
Referencing the compiler used and the object format
Reference the compiler you are using and the format of the object file output
by the compiler.
[Supplementary explanation]
To alter this setting, use the dialog box that is brought up by selecting
"Debug" and then "Debug Settings..." from the menu.
Specifying the method for storing debug information
There are two methods for storing debug information: on memory method
and an on demand method.
Select the method for storing debug information.
(By default, the on memory is selected)
When selecting the on demand method, check the "On Demand" check box.
- On Memory
The debug information is stored in the memory of your computer. This
method is suitable when the size of the load module (user program) is
small.
- On Demand
The debug information is saved to a reusable temporary file. When you
download the same load module for a second time on, the saved debug
information will be reused and the load module can therefore be
downloaded fast. This method is suitable when the size of the load module
(user program) is large.
