USART Registers: UART Mode

UxRXBUF, USART Receive Buffer Register

UxRXBUFx Bits	The receive-data buffer is user accessible and contains the last received
7−0	character from the receive shift register. Reading UxRXBUF resets the
	receive-error bits, the RXWAKE bit, and URXIFGx. In 7-bit data mode,
	UxRXBUF is LSB justified and the MSB is always reset.

UxTXBUF, USART Transmit Buffer Register

UxTXBUFx Bits	The transmit data buffer is user accessible and holds the data waiting to be
7−0	moved into the transmit shift register and transmitted on UTXDx. Writing to
	the transmit data buffer clears UTXIFGx. The MSB of UxTXBUF is not
	used for 7-bit data and is reset.
