Serial peripheral interface (SPI)
Introduction
The Serial Peripheral Interface (SPI) allows full-duplex, synchronous, serial communication
with external devices. An SPI system may consist of a master and one or more slaves or a
system in which devices may be either masters or slaves.
Main features
●
●
●
●
●
●
●
●
●
In slave mode, continuous transmission is not possible at maximum frequency due to the
software overhead for clearing status flags and to initiate the next transmission sequence.

The SPI is connected to external devices through four pins:

Full duplex synchronous transfers (on three lines)
Simplex synchronous transfers (on two lines)
Master or slave operation
6 master mode frequencies (f

SS Management by software or hardware
Programmable clock polarity and phase
End of transfer interrupt flag
Write collision, Master mode fault and overrun flags
SPI control register (SPICR)
SPI control/status register (SPICSR)
SPI data register (SPIDR)
MISO: Master in / slave out data
MOSI: Master out / slave In data
SCK: Serial clock out by SPI masters and input by SPI slaves
SS: Slave select: This input signal acts as a ‘chip select’ to let the SPI master
communicate with slaves individually and to avoid contention on the data lines. Slave
SS inputs can be driven by standard I/O ports on the master Device.
