3.1.5 Changing the Memory Map Setting

Clicking the [Add…] button on the [Memory Mapping] dialog box or clicking the [Modify…] button after

selecting the information on the memory map setting you want to change opens the [Edit Memory Mapping]

dialog box.

Figure 3.5 [Edit Memory Mapping] Dialog Box

Use this dialog box to change the address range and attributes of a memory map.

[From]: Enter the start address of the map range.

[To]: Enter the end address of the map range.

[Setting]: Enter the memory map setting.

The choices given are listed below. The User (external memory) and Emulator (emulation

memory) attributes can be modified.

• User Read-write: Selects an external area that is readable/writable

• User Read-only: Selects an external area that is write-protected

• User Guarded: Selects an external area that is access-prohibited

• Emulator Read-write: Sets readable/writable emulation memory as an external area

• Emulator Read-only: Sets write-protected emulation memory as an external area

• Emulator Guarded: Sets access-prohibited emulation memory as an external area

• No-access Area: Space that includes no memory

Emulation memory can be used as replacement of a ROM or flash memory on the user system. When the user

program accesses to an access-prohibited area or writes to a write-protected area, a break occurs due to the

illegal access. The user can set the [Configuration Properties] dialog box so that an illegal access will cause a

break. Accesses to memory with the debugging function in use, as in the [Memory] window, are available

regardless of the attribute that has been selected.

Note: The setting cannot be changed in the single-chip mode.
