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