The serial peripheral interface (SPI), an independent serial
communications subsystem, allows the MCU to communicate
synchronously with peripheral devices, such as transistor-transistor
logic (TTL) shift registers, liquid crystal (LCD) display drivers, analog-to-
digital converter subsystems, and other microprocessors. The SPI is
also capable of inter-processor communication in a multiple master
system. The SPI system can be configured as either a master or a slave
device, with data rates as high as one half of the E clock rate when
configured as a master and as fast as the E clock rate when configured
as a slave.
The SPI shares I/O with four of port D’s pins and is enabled by SPE in
the SPCR:
