Note: Pins 1, 2, 13, and 14 belong to the STDC14 footprint and are not accessible with a MIPI10 compatible probe.
13.2.2 STDC14 debug connector (option)
The STDC14 debug connector might be implemented, depending on supported tools, for easy interface with ST
tools ecosystem.

If needed, a MIPI10 compatible probe can be plugged into the STDC14 connector (CN11) but you might have to
bend or cut pins 1, 2, 13, and 14.
