2.3.1.5 External Memory Emulation
This section explains the external memory emulation function.
■ External memory emulation
Some DSU4 chips can use the RAM in the adapter unit in place of the user system memory. This function
is called external memory emulation.
For the FR Family, the ‘chip select’ terminal must be specified to access memory outside the chip.
Therefore, when using the external memory emulation function, specify the chip select number.
This function can be controlled using the [External Memory Emulation] tab in debug environment setting
dialog. Select either ROM or RAM as the emulated memory.
For the detailed specifications and setup procedure, refer to the hardware manual for the appropriate
adapter unit.
