Description
Embedded Characteristics
The Universal Synchronous Asynchronous Receiver Transceiver (USART) provides one full
duplex universal synchronous asynchronous serial link. Data frame format is widely programma-
ble (data length, parity, number of stop bits) to support a maximum of standards. The receiver
implements parity error, framing error and overrun error detection. The receiver time-out enables
handling variable-length frames and the transmitter timeguard facilitates communications with
slow remote devices. Multidrop communications are also supported through address bit han-
dling in reception and transmission.
The USART features three test modes: remote loopback, local loopback and automatic echo.
The USART supports specific operating modes providing interfaces on RS485, LIN and SPI
buses, with ISO7816 T = 0 or T = 1 smart card slots 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 DMA Controller, which enables data transfers to the
transmitter and from the receiver. The DMAC provides chained buffer management without any
intervention of the processor.
