4.14 Communication interfaces
The following communication interfaces are implemented:
 UART1: Full feature UART, synchronous mode, SPI master mode, Smartcard mode,
IrDA mode, single wire mode, LIN2.1 master capability
 SPI: Full and half-duplex, 8 Mbit/s
 I²C: Up to 400 kbit/s
4.14.1 UART2
Main features
 1 Mbit/s full duplex SCI
 SPI emulation
 High precision baud rate generator
 Smartcard emulation
 IrDA SIR encoder decoder
 LIN master mode
 LIN slave mode
Asynchronous communication (UART mode)
 Full duplex communication - NRZ standard format (mark/space)
 Programmable transmit and receive baud rates up to 1 Mbit/s (fCPU/16) and capable
of following any standard baud rate regardless of the input frequency
 Separate enable bits for transmitter and receiver
 Two receiver wakeup modes:
– Address bit (MSB)
– Idle line (interrupt)
 Transmission error detection with interrupt generation
 Parity control
Synchronous communication
 Full duplex synchronous transfers
 SPI master operation
 8-bit data communication
 Maximum speed: 1 Mbit/s at 16 MHz (fCPU/16)
LIN master mode
 Emission: Generates 13-bit synch. break frame
 Reception: Detects 11-bit break frame
