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 and PORTD each has one SPI. Notation of these peripherals are SPIC and SPID,
respectively.
