TAG connector CN5

The TAG connector is implemented on the STM32L4 Discovery kit for IoT node. The TAG

connector is a 10-pin footprint supporting SWD mode, which is shared with the same signals

as for the ST-LINK.

The TC2050-IDC-NL cable is used to link ST-LINK and TAG connector on the STM32L4

Discovery kit for IoT node, so that the STM32L4 can be easily programmed and debugged

without any extra accessory.
