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. Note that when debugging the system which operates the MCU with a dual power supply, power cannot

be supplied from the E8a.
