enable the interrupt level (1 to 6) to the transfer interrupt. In the transfer
interrupt program, the receiving operation should be done like the above example
before setting the next transfer data.
Transmission and receiving (Full duplex mode)
When the full duplex mode is used, set the level of receive interrupt to 0 and set
Baud rate = 9600 bps
fc = 14.7456 MHz
