Can I reprogram on-chip Flash rewrite mode & execute control program

Latest Updated:03/22/2012

Question:

Can I reprogram on-chip Flash in the CPU rewrite mode while executing the control program in the boot ROM or user ROM area?

Answer:

It is possible if EW1 mode is used. In EW1 mode, the reprogramming control program in the on-chip ROM area can be executed and the on-chip flash memory can be reprogrammed.
However, the block that contains the reprogramming control program is excluded from the reprogramming.
