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 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.

Flash control/status register (FCSR)
This register is reserved for use by programming tool software. It controls the Flash
programming and erasing operations.
