Reading the RXDATAL Register location
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 USART.CTRLC is set to 9BIT Low byte first, read USART.RXDATAL
before USART.RXDATAH, otherwise always read USART.RXDATAH before USART.RXDATAL in
order to get the correct flags.
