Receiver Data Register Low Byte
The receive buffer consists of a two-level FIFO. The FIFO and the corresponding flags in the high byte of RXDATA will change state whenever the receive buffer is accessed (read). If CHSIZE in USARTn.CTRLC is set to 9BIT Low byte first, read USARTn.RXDATAL before USARTn.RXDATAH. Otherwise, always read USARTn.RXDATAH before USARTn.RXDATAL in order to get the correct flags.
