2.19.7 SERCOM-USART: Collision Detection

In USART operating mode with Collision Detection enabled (CTRLB.COLDEN=1), the SERCOM will not abort the current transfer as expected if a collision is detected and if the SERCOM APB Clock is lower than the SERCOM Generic Clock.

Work Around:

The SERCOM APB clock must always be higher than the SERCOM Generic Clock to support collision detection.
