The Serial Peripheral Interface (SPI) allows high-speed full-duplex, synchronous data transfer
between different devices. Devices can communicate using a master-slave scheme, and data is
transferred both to and from the devices simultaneously.
PORTC, PORTD, PORTE, and PORTF each has one SPI. Notation of these peripherals are
SPIC, SPID, SPIE, and SPIF, respectively.
Four Identical SPI peripherals
