11.3 SERIAL PERIPHERAL INTERFACE (SPI)
11.3.1 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 however the SPI
interface can not be a master in a multi-master
system.

not possible at maximum frequency due to the

11.3.3 General Description
Figure 37
(SPI) block diagram. There are 3 registers:
The SPI is connected to external devices through
3 pins:
– 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 in-
– SS: Slave select:
put by SPI slaves
This input signal acts as a ‘chip select’ to let
the SPI master communicate with slaves indi-
vidually and to avoid contention on the data
lines. Slave SS inputs can be driven by stand-
ard I/O ports on the master MCU.
