4.2.4.1 UPDI using JTAGICE3

The JTAGICE3 supports programming and debugging using the UPDI interface. However, the JTAGICE3 has hardware which is not able to drive the 1-wire UPDI interface on pin 3 (AVR header) without driving pin 6 (AVR header) at the same time. For this reason it is recommended to use the 10-pin mini-squid cable for UPDI.

Note: Atmel-ICE and newer tools are capable of direct connection to the UPDI header.
