// @Description   The master device can initiate the first data transfer by 
//                writing the transmit data into transmit buffer. This value 
//                is copied into the shift register (which is assumed to be 
//                empty at this time), and the selected first bit of the 
//                transmit data is placed onto the MTSR line on the next 
//                clock from the baud rate generator. 
//                A slave device immediately outputs the selected first bit 
//                (MSB or LSB of the transfer data) at pin MRST, when the 
//                contents of the transmit buffer are copied into the slave's
