| Notes | IMPORTANT: R8C/25 Microcomputer Flash Memory Version.This algorithm is written in parallel I/O mode. In the buffer8K-byte Boot ROM is mapped to 0000h-1FFFh.2K-byte Data ROM (block A & B) is mapped to 2400h-2BFFh16K-byte User ROM is mapped to C000h-FFFFh.The User Boot and Data ROMs are selected in the Configure Options.Buffer locations 2000h-23FFh and 2C00h-BFFFh are not used and should be filled with FFh.Buffer locations FFDCh-FFFFh are special. The last byte of User ROM (address FFFFh)containing code protection bits can be set in Device Configure menu and programmed by enablingSecure command.Config Options allow the individual ROM sections to be selected for device operations. Before executingany command at least 1 Operations Area must be selected.The Boot ROM area of the device has a standard serial I/O modecontrol program stored in it when shipped from the factory.It is not necessary to program the boot area for normal use the device may failcommunication if improper data is programmed into the Boot ROM area. |
