Hmm, this sets bit 6 in UCONn to generate an error interrupt upon an exception, but there is no handler for error interrupts registered/implemented, right? However, table 11-1 (Interrupts in Connection with FIFO) says about Error Interrupts in FIFO Mode: > Generated when frame error, parity error, or break > signal are detected. > Generated when it gets to the top of the receive > FIFO without reading out data in it (overrun error). So maybe an overrun error means that the fifo is full and not that we lost a byte? Greetings, Sascha
