The USART features three test modes: remote loopback, local loopback and automatic echo.
The USART supports specific operating modes providing interfaces on, LIN and SPI buses and
infrared transceivers. The hardware handshaking feature enables an out-of-band flow control by
automatic management of the pins RTS and CTS.
The USART supports the connection to the Peripheral DMA Controller, which enables data
transfers to the transmitter and from the receiver. The Peripheral DMA Controller provides
chained buffer management without any intervention of the processor.
