23.2 Overview
The Serial Peripheral Interface (SPI) is a high-speed synchronous data transfer interface using three or four pins. It
allows fast communication between an Atmel AVR XMEGA device and peripheral devices or between several
microcontrollers. The SPI supports full-duplex communication.
A device connected to the bus must act as a master or slave.The master initiates and controls all data transactions.
PORTC has one SPI. Notation of this peripheral is SPIC.
