The flash memory versions of the V850ES/JG3-H and V850ES/JH3-H perform authentication using a 10-byte ID code
Set the ID code in the 10-byte on-chip flash memory area from 0000070H to 0000079H to allow the debugger perform
If the IDs match, the security is released and reading flash memory and using the on-chip debug emulator are enabled.
• 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
