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 implemented in case another device forces the signal. Refer to the Programming Tool
documentation for recommended resistor values.
During the ICC session, the programming tool must control the RESET pin. This can lead to
conflicts between the 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.
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.
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 selected clock option is not programmed in the option
byte. ST7 devices with multi-oscillator capability need to have OSC2 grounded in this case.
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
