About AN3275SW, I encountered some problems I hope to give some answers.In the program does not copy the program to RAM function, then when erasing and programming Flash, the microcontroller is how to run it?
Can you please elaborate on the description of the problems?
I suppose you use S12DP512. This flash consists from 4 flash blocks.
There is one restriction, it is not possible to read from a flash block while it is being erased or programmed.
Therefore, the flash commands are execured from RAM.
