FLASH PROGRAM MEMORY (Cont’d)
4.5 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 us-
ing 36-pulse mode.
Depending on the ICP code downloaded in RAM,
Flash memory programming can be fully custom-
ized (number of bytes to program, program loca-
tions, or selection serial communication interface
for downloading).
When using an STMicroelectronics or third-party
programming tool that supports ICP and the spe-
cific microcontroller device, the user needs only to
implement the ICP hardware interface on the ap-
plication board (see Figure 7). For more details on
the pin locations, refer to the device pinout de-
scription.
4.6 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, (us-
er-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 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 pro-
tected to allow recovery in case errors occur dur-
ing the programming operation.
4.7 Related Documentation
For details on Flash programming and ICC proto-
col, refer to the ST7 Flash Programming Refer-
ence Manual and to the ST7 ICC Protocol Refer-
ence Manual
