In-circuit debugging connection with ICD adapter
UM0139
CLKIN solder point (G2)
Your in-circuit debugging tool can provide the clock signal for initiating in-circuit
communication with the microcontroller on the ICD adapter. To do this, you must complete
the connection with a drop of solder on the CLKIN solder point (G2) shown in Figure 18.

Solder point G2
When the solder drop is placed on the CLKIN solder point (G2), pin PA5 is relayed to CLKIN
on the ICC connector. PA5 is not available for the application.
When the clock signal is furnished by the in-circuit debugging tool, use the Option Bytes
Disabled mode to start the in-circuit debugging session. For further information about this
mode refer to the online help of your integrated development environment or debugging
software.

Run the application in standalone mode
Once the microcontroller on the ICD adapter has been programmed during an in-circuit
debugging or in-circuit programming session, it can run the application in place of the target
microcontroller without being connected to an in-circuit debugging tool or the host PC.

To run the application in standalone mode, the RST/PA3 On jumper (TP2) must be fitted
and the ICD On jumper (TP1) must not be fitted.
