13.3 TAG connector (CN3)
A Tag-connect™ 10-pin footprint is implemented on the top side of STM32U5A9J-DK (on the border of the PCB).
The TC2050-IDCNL cable can be used to connect to the STM32U5A9J-DK Discovery kit.
Attention: Before using CN3, check specific constraints in Section 12.14 SWD debug/program/trace and JTAG/USART.
