Erase of flash memory
If the On-Chip Debug Option Byte is set to "Do not erase data of flash memory in
case of failures in enabling on-chip debugging" and if you forget the security ID,
you need to erase the flash memory completely.
Ｔ o erase the flash memory, please follow the steps below.
Double-click to open the file "exk0r32ocfg.exe" under the directory "C:¥Program
Files¥NEC Electronics Tools¥TK-driver" (as the installation directory is default).
"78K0R Starter Kit Setting" starts.
Set "Flash Memory" to " Erase flash memory at debugger start up ", then click "Setting".
Restart the integrated debugger (ID78K0R-QB).
Now the ID code is the default value of 0xFFFFFFFFFFFFFFFFFFF.
Input
「
FFFFFFFFFFFFFFFFFFFF
」
When you could confirm the debugger is working, open "exk0r32ocfg.exe" again. This time,
select "KEEP flash memory at debugger start up", then click Setting.
(Because there is a limit of erasing times for flash memory, it is recommended to try not to
erase the flash memory too many times).
If you want to change the Security ID code to your favorite secret code, please
input the secret code in the Linker option. Then, you will compile the program.
After then, you have to input your secret security code everytime your starting up
the debugger. If you input a wrong code, you will find the ollowing warning.
