5.5.1 Map Command
The memory map information must be altered to suit the target microcomputer's memory space by
Map command.

• Internal
Enables the emulator's internal resources. The internal ROM area must be set for Internal
because it is always emulated with the emulator's internal resources. If an external area is not
allocated memory, you can use the emulator's internal memory by setting that area for Internal.
• External
Enables resources external to the emulator (including the internal SFR and RAM areas). The
internal SFR and internal RAM areas must always be set for External. To enable the memory
allocated for an external area, set that area for External.
The memory map attributes immediately after the emulator has started up are External for
0h-3FFFh and Internal for 4000h-FFFFh. Use the MAP command to look up or alter the memory map
information. Execute the MAP command from the script window.
ATTENTION
•
[the case that the internal ROM area is located to the address before 4000h]
If the internal ROM area of the target mcu is located to the address before 4000h, please change
the mapping of this area to INTERNAL.
Example)
when the internal ROM area is located from 1080h:
1080 to 3FFF -> Internal
•
[About special settings when using the M38000TL2-FPD]
Always set the internal SFR and internal RAM areas for External. However, if the target MCU's
RAM area is larger than the RAM included in the emulator MCU, set that area for Internal.
Example)
When the RAM area included in the emulator MCU is 40-1FF and the target MCU's internal
RAM area is 40-2FF
40 to 1FF -> External
200 to 2FF -> Internal
