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, PORTD, PORTE, and PORTF each have two USARTs. Notation of these peripherals
are USARTC0, USARTC1, USARTD0, USARTD1, USARTE0, USARTE1, USARTF0,
USARTF1.
