E8a Emulator
Section 7 Debugger Setting
[Mode]
- Erase Flash and Connect
When starting the debugger, the E8a emulator erases the Flash memory data for the MCUs and simultaneously
writes the E8a emulator program.
- Keep Flash and Connect
When launching the debugger, the E8a emulator retains the Flash memory data for the MCUs. Note that the area
for the E8a emulator program and the vector area used by the E8a emulator will change.
- Program Flash
The E8a emulator starts as a simple programmer. When downloaded, the E8a writes only the user program (E8a
emulator program is not written). Therefore, the program cannot be debugged in this mode.
- Debugging of CPU rewrite mode
Select this setting when debugging the program which rewrites the CPU. In this mode, the following debug
operation which rewrites the Flash memory cannot be executed.
- Setting the PC break points
- Changing the memory contents in the Flash memory area
In this mode, when starting the debugger, the E8a emulator erases the Flash memory data for the MCUs and
simultaneously writes the E8a emulator program.
When [Execute the user program after ending the debugger.] is selected, with the E8a emulator connected to the user
system, the user program is executed at the same time the debugger is terminated. This check box setting is available
only when the [Program Flash] mode is selected.
[Power supply]
When supplying power to the user system from the E8a, click the [Power Target from Emulator. (MAX 300mA)]
check box.
3. [Firmware Location] tab
For details, see “1. Program area for the E8a emulator” in “Section 6. Notes on Using the E8a Emulator”.
4. [Communication Baud Rate] tab
Select communication baud rate between the E8a and MCU in the [Communication Baud Rate] tab. 500000bps
(default setting) should be selected during normal use.
