Reading the USARTn.RXDATAL Register will
return the contents of the Receive Data Buffer register (RXB).
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.
