1. If the ICCCLK or ICCDATA pins are only used as outputs in the application, no signal isolation is necessary. As soon as the
2. During the ICC session, the programming tool must control the RESET pin. This can lead to conflicts between the
3. The use of Pin 7 of the ICC connector depends on the programming tool architecture. This pin must be connected when
4. Pin 9 has to be connected to the OSC1 (or OSCIN) pin of the ST7 when the clock is not available in the application or if the

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

programming tool and the application reset circuit if it drives more than 5mA at high level (push-pull output or pull-up
resistor < 1K). A schottky diode can be used to isolate the application reset circuit in this case. When using a classical RC
network with R > 1K or a reset management IC with open drain output and pull-up resistor > 1K, no additional components
are needed. In all cases the user must ensure that no external reset is generated by the application during the ICC session.
