Latest Updated:03/25/2009

Question:

Is it possible to execute a program on the external memory and erase/rewrite to the on-chip flash memory in the user programming mode?

Answer:

Yes, it is possible.
However, it is necessary to control the wait time, when erasing or rewriting to the on-chip flash memory. Please note that the access time of the external memory needs to be considered, if the wait time is controlled by a software timer.
