4.5 Universal Synchronous and Asynchronous Receiver and Transmitter (USART) Setup

For verification and testing purposes, it can be helpful to transmit data to a serial terminal for visualization. To configure the USART to send data over its TX (transmit) pin, it is required to only enable the transmitter, set the baud rate, and configure the USART TX pin as an output. By using the USART driver provided by Atmel START, the baud rate is calculated and configured by the driver.
