Configuration batch file
The example batch file below sets the mode vector and sets up the CS0 configuration register for the download
area. Use values appropriate to the hardware in the wait, timing, and other settings.

Emulation memory
If SRAM as the emulation memory is built on target board, SRAM for be accessed by RD, WR signal, and
+BYTE
control signal can not be used. (The external bus is initialized to the bus mode for accessing RD, WRn after reset.)
