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, (user-defined strategy for entering programming mode, choice of
communications protocol used to fetch the data to be stored, etc.). For example, it is
possible to download code from the SCI or other type of serial 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.

Reference Manual and to the ST7 ICC Protocol Reference Manual
Register description
Flash Control/status register (FCSR)
This register is reserved for use by programming tool software. It controls the Flash
programming and erasing operations.
