Product overview

108

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)

4.14.2

Serial peripheral interface (SPI)

•

Maximum speed: 8 Mbit/s (fMASTER/2) both for master and slave

•

Full duplex synchronous transfers

•

Simplex synchronous transfers on two lines with a possible bidirectional data line

•

Master or slave operation - selectable by hardware or software

•

CRC calculation

•

1 byte Tx and Rx buffer

•

Slave /master selection input pin

4.14.3

Inter integrated circuit (I2C) interface

•

I2C master features:

–

Clock generation

–

Start and stop generation

•

I2C slave features:

–

Programmable I2C address detection

–

Stop bit detection

•

Generation and detection of 7-bit/10-bit addressing and general call

•

Supports different communication speeds:

–

Standard speed (up to 100 kHz),

–

Fast speed (up to 400 kHz)
