must configure the PIO Controller before enabling the transmitter or receiver.
Description
USART Serial clock can be configured as input or output:
SCK is configured as input if an External clock is selected (USCLKS[1] = 1)
SCK is driven as output if the External Clock is disabled (USCLKS[1] = 0) and Clock output is enabled (CLKO = 1)
Transmit Serial Data is an output
Receive Serial Data is an input
