The Universal Synchronous and Asynchronous serial Receiver and Transmitter (USART) pro-
vides highly flexible serial communication device. The frame format can be customized to
support a wide range of standards, and the USART implements different error detection.
PORTC and PORTD each have two USARTs. PORTE has one USART. Notation of these
peripherals are USARTC0, USARTC1, USARTD0, USARTD1, and USARTE0.
