Description
Cloned from #4577:
The UART/USART of the ATSAM doesn't have any FIFO buffer. Therefore every received character has to be processed before the next one arrives. In situations with a high interrupt load or during long interrupt locks, this might not work reliable and the UART/USART can loose characters.
