4.6
IAP (in-application programming)
This mode uses a BootLoader program previously stored in Sector 0 by the user (in ICP
mode or by plugging the device in a programming tool).
This mode is fully controlled by user software. This allows it to be adapted to the user
application, (such as user-defined strategy for entering programming mode, choice of
communications protocol used to fetch the data to be stored). For example, it is possible to
download code from the serial peripheral or serial communication interface and program it in
the Flash. IAP mode can be used to program any of the Flash sectors except Sector 0,
which is write/erase protected to allow recovery in case errors occur during the
programming operation.
