Routing The Cs0-Line To The External Ram Of The Emulation Adapter Board; Configuration Of The Debugger - Fujitsu FR Series Application Note

Fujitsu provides a set of batch files (start_ram.prc, etc.), which can be called form the
debugger of Softune Workbench. "start_ram.prc" is the main procedure file which calls other
procedure files as
PLL_32MHz.prc and set_EVA_mode.prc.
The sequence of "start_ram.prc" sets the mode byte and reset-vector to dedicated values in
external memory. When mode pin MD0 is set to high (dipswitch S1:MD0 to OFF) these
values are read at the next reset and set the MCU to external ROM-mode.
After power on of the evaluation board, the following sequence should be kept to set the
MCU in the external ROM-mode.

3.2 Configuration of the debugger

In the debugger configuration, a procedure file can be specified which is started before the
code is loaded to the emulator. Choose the batch file "start_ram.prc". It is useful to disable
the automatic loading of the application at start of the debugger.
