Typical Connection ( SPI [OPTION] )
SPI Serial Peripheral Interface (Original SPI)
The Serial Peripheral Interface (SPI) is a 4-wire Clock Synchronous Serial Interface. It
is designed to easily connect any CPU to SPI compliant slaves using only 3 lines plus one chip
select line per slave. Few slaves can be connected on the CPU SPI. The 4 required lines on the
slave side for the SPI are MISO, MOSI, SCK signal and /SS signal.
