3.15

USART

The USART interface (USART) allows full duplex, asynchronous communications with

external devices requiring an industry standard NRZ asynchronous serial data format. It

offers a very wide range of baud rates.

3.16

SPI

The serial peripheral interface (SPI) provides half/ full duplex synchronous serial

communication with external devices. It can be configured as the master and in this case it

provides the communication clock (SCK) to the external slave device. The interface can also

operate in multi-master configuration.

3.17

I²C

The inter-integrated circuit (I2C) Bus Interface is designed to serve as an interface between

the microcontroller and the serial I2C bus. It provides multi-master capability, and controls all

I²C bus-specific sequencing, protocol, arbitration and timing. It manages standard and fast

speed modes.
