[7:0] Receive data for UART
This field contains the data received over the single channel
UART.
When the UART finishes receiving a data frame, the receive data
ready bit in the UART status register, USTAT[5], should be "1".
This prevents reading invalid receive data that may already be
present in the URXBUF.
Whenever the URXBUF is read, the receive data ready
bit(USTAT[5]) is automatically cleared to "0".
