Overview
The Universal Synchronous and Asynchronous serial Receiver and Transmitter (USART) is a
highly flexible serial communication module. The USART supports full duplex communication,
and both asynchronous and clocked synchronous operation. The USART can also be set in
Master SPI mode to be used for SPI communication.
Communication is frame based, and the frame format can be customized to support a wide
range of standards. The USART is buffered in both direction, enabling continued data transmis-
sion without any delay between frames. There are separate interrupt vectors for receive and
transmit complete, enabling fully interrupt driven communication. Frame error and buffer over-
flow are detected in hardware and indicated with separate status flags. Even or odd parity
generation and parity check can also be enabled.
One USART can use the IRCOM module to support IrDA 1.4 physical compliant pulse modula-
tion and demodulation for baud rates up to 115.2 kbps.
PORTC, PORTD, and PORTE each has two USARTs, while PORTF has one USART only.
Notation of these peripherals are USARTC0, USARTC1, USARTD0, USARTD1, USARTE0,
USARTE1 and USARTF0, respectively.
