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
•High-speed 5- to 9-bit full-duplex synchronous serial communication
•RS485 with driver control signal
•ISO7816, T0 or T1 protocols for interfacing with smart cards
•InfraRed IrDA Modulation and Demodulation
•Test modes
SPI Mode
– Master or Slave
– Serial Clock Programmable Phase and Polarity
– SPI Serial Clock (CLK) Frequency up to Internal Clock Frequency CLK_USART/4
–MSB- or LSB-first
–1, 1.5 or 2 stop bits
–Parity even, odd, marked, space or none
–By 8 or by 16 over-sampling receiver frequency
–Optional hardware handshaking
–Optional break management
–Optional multidrop serial communication
