Figure 11.3.1 Flow chart before storing transmitting data in Asynchronous transmit FIFO
Note1: Store the data to be transmit previously in Asynchronous transmit FIFO.
Note2: If the transmitting length is below the digit of quadret, write "0" there up to quadret unit.
Note3: The device can automatically attaches CRC code.
