I have a system with an R8C1B up and running except for the Data FLASH. I have attempted to implement code similar to the app note R01AN0109EJ0100 "R8C/2D Group - Rewriting the Data Flash Using the Suspend Function in EW1 Mode", to no avail. I had hoped that this was similar enough to the 1B, but, the code seems to be lacking. I can erase and get a successful status back from the status check, and I get a successful status on a write when I write 0xA5. However, when I read, I still get 0xFF in stead of 0xA5. I do not see any means or mention of enabling the Data FLASH, but, it seems that I am missing something. I have used Data FLASH in the R8CM12, but, that is not similar to the 1B.
Can anyone offer any advice? The older links, that might have been useful, in the FAQs section are inactive.
