Virtual COM port connector

The CN3 connector allows the connection of a target UART for Virtual COM port function.
The debug connection (through JTAG/SWD or SWIM) is not required at the same time.
However, a GND connection between STLINK-V3SET and target is required and must be
ensured in some other way in case no debug cable is plugged. The related pinout for the
VCP connector is listed in

Table 8

.

8.2.4 SWIM

connector

The CN4 connector allows the connection to an STM8 SWIM target. The related pinout for
the SWIM connector is listed in
