[7:0] Transmit data for UART
This field contains the data to be transmitted over the single
channel UART.
When this register is written, the transmit buffer register empty bit
in the status register, USTAT[6], should be "1". This is to prevent
overwriting of transmit data that may already be present in the
UTXBUF.
Whenever the UTXBUF is written with a new value, the transmit
register empty bit, USTAT[6], is automatically cleared to "0".
