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 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.
