FIRE Emulator for H8S and H8/300H 7 Q u i c k S t a r t

Here a typical example, how to setup the system:

1. Set cpu-type and -mode options

The command sys.cpu is used to select one derivative within a cpu-family and to set its operation

mode.

2. Set system options

The system window controls the CPU specific setup. Please check this window very carefully and set

the appropriate options. Use the button in the main tool bar and click to the option check box

(Command: HELP.PICK) to get online help in a pop up window.

3. Select dualport mode (optional)

Dualport allows access to emulation RAM, while emulation is running. This is necessary to display

variables, set breakpoints or display the flag listings while the emulation is running. System.Access

selects how dualport access is done.

4. Set mapper (optional)

The mapper controls the memory access of the CPU. This means the use of internal or external

memory, the protection of a memory bank etc. Address ranges must be defined by using memory

classes.
