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 be set in Master
SPI compliant mode and 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.
A block diagram of the USART is shown in
Clock Generator, the Transmitter and the Receiver, indicated in dashed boxes.
