SAM9N12
– 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
• Test Modes
– Remote Loopback, Local Loopback, Automatic Echo
9.24 Universal Asynchronous Receiver Transmitters (UART)
•Two UARTs
• Independent receiver and transmitter with a common programmable Baud Rate Generator
• Even, Odd, Mark or Space Parity Generation
