In-application programming (IAP)
Related documentation
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, ...). For example, it is possible
to download code from the SPI, SCI, USB or CAN 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.
For details on Flash programming and ICC protocol, refer to the ST7 Flash programming
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.
