  Serial Peripheral Interface
  
     <communications, hardware> (SPI) A serial interface in which
     a master device supplies clock pulses to exchanges data
     serially with a slave over two data wires (Master-Slave and
     Slave-Master).  This term probably originated with Motorola in
     about 1979 with their first all-in-one microcontroller.
