Caution After the flash memory is erased, 1 is written to the entire area.
The flash memory versions of the V850E/IF3 and V850E/IG3 perform authentication using a 10-byte ID code to
Set the ID code in the 10-byte on-chip flash memory area from 0000070H to 0000079H to allow the debugger
If the IDs match, the security is released and reading flash memory and using the on-chip debug emulator are
• Set the 10-byte ID code to 0000070H to 0000079H.
• Bit 7 of 0000079H is the on-chip debug emulator enable flag.
• When the on-chip debug emulator is started, the debugger requests ID input. When the ID code input on the
