5.3.6 Serial Peripheral Interface Controller (SPI)
The SAMA5D3 series processor provides two high-speed Serial Peripheral Interface (SPI) controllers.
One port is used to interface with the on-board serial DataFlash®.
There are four main signals used in the SPI interface: Clock, Data In, Data Out, and Chip Select. The
Serial Peripheral Interface (SPI) is a serial interface similar to the IIC bus interface but with three primary
differences:
„ it operates at a higher speed,
„ separate transmit and receive data lines,
„
device access is chip-select based instead of address based.
