3.14 Universal synchronous/asynchronous receiver transmitters
(USART)
The device embeds one universal synchronous/asynchronous receiver transmitter
(USART1), which communicate at speeds of up to 6 Mbit/s.
It provides hardware management of the CTS, RTS and RS485 DE signals, multiprocessor
communication mode, master synchronous communication and single-wire half-duplex
communication mode. USART1 supports also SmartCard communication (ISO 7816), IrDA
SIR ENDEC, LIN Master/Slave capability and auto baud rate feature, and has a clock
domain independent from the CPU clock, allowing to wake up the MCU from Stop mode.
The USART interface can be served by the DMA controller.
