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.
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.
I²C
The inter-integrated circuit (I2C) bus interface is designed to serve as an interface between
the microcontroller and the serial I
I²C bus-specific sequencing, protocol, arbitration and timing. It manages standard and fast
speed modes.
