Caution:
ICC interface
ICC needs a minimum of 4 and up to 6 pins to be connected to the programming tool (see

Figure 8.
1. If the ICCCLK or ICCDATA pins are only used as outputs in the application, no signal isolation is
2. During the ICC session, the programming tool must control the RESET pin. This can lead to conflicts
3. The use of Pin 7 of the ICC connector depends on the programming tool architecture. This pin must be

External clock ICC entry mode is mandatory in ST72F324B 8/16 Kbyte Flash devices. In
this case pin 9 must be connected to the OSC1 (OSCIN) pin of the ST7 and OSC2 must be
grounded. 32 Kbyte Flash devices may use external clock or application clock ICC entry
mode.

the application, isolation such as a serial resistor has to be implemented in case another device forces the

drain output and pull-up resistor >1 kΩ, 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.
