E8a Emulator Section 7 Debugger Setting

4. [MCU Setting] Tab

In the [MCU Setting] tab, set the operating condition of the MCU used in the user system.

Figure 7.3 [MCU Setting] Tab

Specify processor mode

Specify the processor mode according to the user system. One of the following can be specified:

- Single-Chip Mode

- Memory Expansion Mode

Memory Expansion Mode

When Memory Expansion Mode is selected, specify whether the memory space expansion function will be used.

When using the memory space expansion function, select “4 MB Mode”, and when not using, select “Normal

Mode”.

PM13 (b3 of 000005H) is ‘1’

Specify whether PM13 (third bit of processor mode register 1) is set. When using the user program with PM13 set

to “1”, check this option.

PM10 (b0 of 000005H) is ‘1’

Specify whether PM10 (zero bit of processor mode register 1) is set. When using the user program with PM10 set

to “1”, check this option.

Notes:

The following describes precautions to be taken when using the emulator in memory expansion mode:

- When the external area cannot be rewritten via normal memory access, software breaks cannot be used in that area.

- No address match break can be used in the external memory space.

- The “Go to Cursor” function cannot be used in the external memory space. If this function is used in the external

memory space, the program will be in a state of execution.

- To access the memory space expansion area in the download, the editor window (MIX display or disassembled

display mode), the memory window or the watch window while operating in the memory space expansion 4 MB

mode, be aware that only bank 7 can be accessed. In this case, the data bank offset depends on the offset bits of the

data bank register.

- When using the memory space expansion function 4 MB mode, execute the command for the memory space

expansion function 4 MB mode to access each bank.
