Universal Asynchronous Receiver Transmitters (UART)
SAM9G35
• RS485 with driver control signal
• ISO7816, T = 0 or T = 1 Protocols for interfacing with smart cards
• IrDA modulation and demodulation
• SPI Mode
• LIN Mode
• Test Modes
• Two UARTs
• Independent receiver and transmitter with a common programmable Baud Rate Generator
• Even, Odd, Mark or Space Parity Generation
• Parity, Framing and Overrun Error Detection
• Automatic Echo, Local Loopback and Remote Loopback Channel Modes
– MSB- or LSB-first
– Optional break generation and detection
– By 8 or by-16 over-sampling receiver frequency
– Hardware handshaking RTS-CTS
– Receiver time-out and transmitter timeguard
– Optional Multi-drop Mode with address generation and detection
– Optional Manchester Encoding
– NACK handling, error counter with repetition and iteration limit
– Communication at up to 115.2 Kbps
– Master or Slave
– Serial Clock Programmable Phase and Polarity
– SPI Serial Clock (SCK) Frequency up to Internal Clock Frequency MCK/4
– Compliant with LIN 1.3 and LIN 2.0 specifications
– Master or Slave
– Processing of frames with up to 256 data bytes
– Response Data length can be configurable or defined automatically by the Identifier
– Self synchronization in Slave node configuration
– Automatic processing and verification of the “Synch Break” and the “Synch Field”
– The “Synch Break” is detected even if it is partially superimposed with a data byte
– Automatic Identifier parity calculation/sending and verification
– Parity sending and verification can be disabled
– Automatic Checksum calculation/sending and verification
– Checksum sending and verification can be disabled
– Support both “Classic” and “Enhanced” checksum types
– Full LIN error checking and reporting
– Frame Slot Mode: the Master allocates slots to the scheduled frames automatically.
– Generation of the Wakeup signal
– Remote Loopback, Local Loopback, Automatic Echo
