Whether transmit data is output/input at the rising edge or falling edge of the
transfer clock can be selected
Whether transmission/reception begins with bit 0 or bit 7 can be selected
Reception is enabled simultaneously by a read from the receive buffer register
UART1 transfer clock can be chosen by software to be output from one of
