MB91461 Emulation

Chapter 2 Evaluation system with MB91V460

Figure 4: Enable external memory emulation

Enable external memory emulation for chip select 0 area as RAM type. This will force the

evaluation MCU to use the external SRAM on MB2198-300, which is connected to the

external bus, as memory for the debug session.

If you use the template project for project startup, the *.sup file calls two procedure files

when starting debug session. Before the code is loaded to external emulation RAM, the prc-

file 'Ext_Emu_RAM_before_load.prc' initializes the memory area for code download. After

the download, prc-file 'Ext_Emu_RAM_after_load.prc' is called which initializes the MCU for

run mode.

This type of emulation system has the advantage that you can debug directly on your target

system without the need of a connector socket for the DSU cable on the target system itself.

You only have to mount a socket instead of the MB91461R chip for connection of the header

board. Because of the usage of the external emulation memory you can use full 8MB size,

not caring about the amount of memory connected on your target system.
