The relationship between the frequences of the TxC and RxC clock 
inputs and the baud rate of the transmitter and receiver is:

       Clock frequency = Baud rate factor x Baud rate

If 10 is in the LSBs of the mode register and the transmitter and 
receiver baud rates are to be 300 and 1200, respectively, then the
frequency applied to: ___
                      TxC should be 4800 Hz and the frequency at 
                      ___
                      RxC should be 19.2 kHz.
