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.
CAUTION
Cautions to Be Taken for Power Supply:
Before carrying out the power supply, check the power specification of the user system and there is
no short circuit in the user system. Incorrect operation will damage the user system and the emulator
product. The user program will be lost.
8. The [Connecting] dialog box is displayed and the emulator connection is started.
