Flash Memory
Chapter 6
6.3 Flash Programming via N-Wire
The microcontroller’s flash memory is programmable via the N-Wire debug
interface.
Programming of the flash memory can be performed by the debug tool running
on the host machine.
Caution
Programming the flash memory during debug sessions by the debug tool adds
to the performed number of write/erase cycles of the flash memory.
Thus devices used for debugging shall not be used for mass production
purposes afterwards.
