Flash program memory
Depending on the ICP driver code downloaded in RAM, Flash memory programming can be
fully customized (number of bytes to program, program locations, or selection of the serial
communication interface for downloading).
4.3.2
In-application programming (IAP)
This mode uses an IAP driver program previously programmed in Sector 0 by the user (in
ICP mode).
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 or choice of
communications protocol used to fetch the data to be stored, etc.).
IAP mode can be used to program any memory areas except Sector 0, which is write/erase
protected to allow recovery in case errors occur during the programming operation.
4.4
ICC interface
ICP needs a minimum of 4 and up to 6 pins to be connected to the programming tool. These
pins are:
RESET:
device reset
VSS:
device power supply ground
ICCCLK:
ICC output serial clock pin(a)
ICCDATA: ICC input serial data pin
CLKIN:
main clock input for external source
VDD:
application board power supply(b)
a.
If the ICCCLK or ICCDATA pins are only used as outputs in the application, no signal isolation is necessary. As
soon as the programming tool is plugged to the board, even if an ICC session is not in progress, the ICCCLK
and ICCDATA pins are not available for the application. If they are used as inputs by the application, isolation
such as a serial resistor has to be implemented in case another device forces the signal. Refer to the
programming tool documentation for recommended resistor values.
b.
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.
