4.8 MMDS0508 Menu Entries

If you have checked the Auto Select according MCU-IDcheckbox, the system automatically loads the default personality file for the MCU-ID. If this checkbox is clear, the system automatically loads the most recently opened or saved memory map file.

You can use the Memory Configuration dialog box to modify the memory configuration, then save this new configuration into a memory configuration file. (Click the Save button.)

You can use the Memory Configuration dialog box to load a different memory configuration file (one that you previously defined and saved). (Click the Open button.)

Another way to load personality files (or any memory configuration files) is to enter the LOADMAP command in the command line.

4.8.3.1 Dual-Port RAM

The Dual-Port RAM area lets you specify the base address and enable “Real-Time Memory”.

To specify the base address, enter the desired value in the Base Address edit box. To Enable the “Real-Time Memory”, check the Enable checkbox. The size of the “Real- Time Memory” is frozen at 1 kilobyte.

Also see the M68MMDS05/08, Motorola Modular Development System, User's Manual for further information.

4.8.3.2 Memory

The Memory area lets you specify the “Real-Time Memory”. For the MMDS0508, this is dual-ported memory that you can assigned to any valid RAM or ROM address. While the MMDS0508 is running, the debugger can display and modify this “Real- Time Memory.” However, if a portion of this memory overlays internal MCU I/O, RAM, or EEPROM, the Memory Configuration dialog box can only display, not monitor, that memory portion.

4.8.4 Signals Emulation

To specify MMDS0508 emulator signals, choose the MMDS0508>Emul Signals...

menu selection. This opens the Target Signals dialog box show in Figure 4.14.
