Communication interfaces

4.14

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

UART1

4.14.1

Main features

• One Mbit/s full duplex SCI

• SPI emulation

• High precision baud rate generator

• Smartcard emulation

• IrDA SIR encoder decoder

• LIN master mode

• Single wire half duplex 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)
