36.6 Functional Description
The USART is capable of managing several types of serial synchronous or asynchronous
communications.
It supports the following communication modes:
⢠5- to 9-bit full-duplex asynchronous serial communication
â MSB- or LSB-first
â 1, 1.5 or 2 stop bits
â Parity even, odd, marked, space or none
â By 8 or by 16 over-sampling receiver frequency
â Optional hardware handshaking
â Optional break management
â Optional multidrop serial communication
⢠High-speed 5- to 9-bit full-duplex synchronous serial communication
â MSB- or LSB-first
â 1 or 2 stop bits
â Parity even, odd, marked, space or none
â By 8 or by 16 over-sampling frequency
â Optional hardware handshaking
â Optional break management
â Optional multidrop serial communication
⢠RS485 with driver control signal
⢠ISO7816, T0 or T1 protocols for interfacing with smart cards
â NACK handling, error counter with repetition and iteration limit
⢠InfraRed IrDA Modulation and Demodulation
⢠Test modes
â Remote loopback, local loopback, automatic echo
