E8a Emulator User's Manual 3. Preparation before Use

Note: The emulator occupies the user’s flash memory area according to the target MCUs. For

details, refer to the additional document, Notes on Connecting the xxxxx.

⎯ Keep Flash and Connect

This mode is used to activate the debugger while retaining data of the MCU flash memory.

However, areas for the emulator program and vector areas used by the emulator will be

changed.

⎯ Program Flash

This mode is used when the emulator is used as a flash memory programmer. It cannot be

used for debugging programs.

Note: It is necessary to input the ID code of the flash memory by the target device. For details,

refer to the additional document, Notes on Connecting the xxxxx.

⎯ Debugging of CPU rewrite mode

This mode is used to debug the program that rewrites the CPU. In this mode, the following

debug operations, which require reprogramming of the flash memory, are not available:

- Setting the PC breakpoint

- Changing the memory contents in the flash memory area

The debugger is activated by erasing data of the MCU flash memory. A program for the

emulator program is also written to at the same time.

Note: This mode is not supported in the H8/Tiny or H8/Super Low Power series.

When the [Execute the user program after ending the debugger.] check box is selected, the user

program is executed at the same time as the debugger operation is ended with the emulator

connected to the user system. This check box is only available when the [Program Flash] mode

has been selected.

When the [Power Target from Emulator. (MAX 300mA)] check box is selected, power will be

supplied to the user system up to 300 mA. Then select 3.3 V or 5.0 V according to the power

voltage of the user system.
