(> 1 k

Ω) , no additional components are needed. In any case, the user must ensure that an

external reset is not generated by the application during the ICC session.

3. The use of Pin 7 of the ICC connector depends on the Programming Tool architecture. This pin

must be connected when using most ST programming tools (it is used to monitor the

application power supply). Please refer to the Programming Tool manual.

5.6

In-Application Programming (IAP)

This mode uses a Boot Loader 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 either DDC

interface and program it in the Flash memory. 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.
