I'm trying to use SCI port on TMS320F2812 as UART with FIFO enabled. The idea of having FIFO is to reduce the interrupt burden for every character. If received characters are less than FIFO size and receive line is idle for a long time then those characters are stuck in FIFO. Processor won't get interrupt for those characters until FIFO gets full. > From my experience with different UART
