I want to use only 1 KB memory as data storage from the flash memory of the SST 89E516RD. I have no idea about how to erase and write into flash for data storage. In the 89E516RD there is some thing written in datasheet as ROM : 64 + 8 KB . But I can't understand it. Also mention how to reserve some memory from flash for data storage. Please provide sample code if possible. Thanks.
Wouldn't it be better if you ask the chip manufacturer for sample code? Or do you think Keil is responsible for how different processors implement their functionality, just because Keil sells development tools?
By the way - have you verified that the chip manufacturer doesn't already have application notes and sample code available?
