Hello!

 

I use 'S9S12GN48F0CLF' and want to use the EEPROM memory protection function.

 

Relative contents are in page.886~ of "MC9S12G Family Reference Manual and Data Sheet Rev.1.27"

 

I set  bit7 of 'EEPROT' before writing to the EEPROM, and clear it after writing.

 

There was no problem when testing in the debug environment, but when it is not, the data could not be stored in the EEPROM.

 

Am I using this function properly?

 

Sorry for my bad english..

 

I look forward to your prompt reply.
