Found some info online, after looking for SERCOM. I guess this is the same for samd21? So my question is: Is there, for SAMD21, a way to get notified by a real interrupt when data is received on UART? If yes: Could you please point me to some helpful - beginner friendly - documentation? Every time the SERCOM (configured as a UART) receives a character, it calls its associated SERCOM.

Often a peripheral pad can be mapped to more than one pin, and many peripherals have a group of pads (ie: SERCOM). So, wow, 6 SERCOMs, totally configurable - best thing ever! So what's the catch? It's just a little one really - when setting up the SERCOM you have to configure what pins it will use (you have many options) and it takes a little time to look up the exact multiplexing setup and make sure you have it right. USB peripheral support in the SAM D21 device offers both peripheral device and embedded host modes having eight endpoints/pipes (each address having one input and one output endpoint).
