ICP (in-circuit programming)
To perform ICP the microcontroller must be switched to ICC (in-circuit communication) mode
by an external controller or programming tool.
Depending on the ICP code downloaded in RAM, Flash memory programming can be fully
customized (number of bytes to program, program locations, or selection serial
communication interface for downloading).
When using an STMicroelectronics or third-party programming tool that supports ICP and
the specific microcontroller device, the user needs only to implement the ICP hardware
interface on the application board (see
to the device pinout description.
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 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.
