Bit Name
This field contains the data to be transmitted over the single
channel Console UART.
When this register is written, the transmit data register empty bit in
the status register, CUSTAT[18], should be '1'. This is to prevent
overwriting of transmit data that may already be present in the
CUTXBUF.
Whenever the CUTXBUF is written with a new value, the transmit
register empty bit, CUSTAT[18], is automatically cleared to '0'.
