SERIAL PERIPHERAL INTERFACE (SPI)
10.7 SERIAL PERIPHERAL INTERFACE (SPI)
10.7.1 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 or a system in
which devices may be either masters or slaves.
The SPI is normally used for communication be-
tween the microcontroller and external peripherals
or another Microcontroller.
Refer to the Pin Description chapter for the device-
specific pin-out.

10.7.3 General Description
The SPI is connected to external devices through
4 alternate function pins:

To use any of these alternate functions (input or
output), the corresponding I/O port must be pro-
grammed as alternate function output.
A basic example of interconnections between a
single master and a single slave is illustrated on
Figure
The MOSI pins are connected together as are
MISO pins. In this way data is transferred serially
between master and slave.
When the master device transmits data to a slave
device via MOSI pin, the slave device responds by
sending data to the master device via the MISO
pin. This implies full duplex transmission with both
data out and data in synchronized with the same
clock signal (which is provided by the master de-
vice via the SCK pin).
Thus, the byte transmitted is replaced by the byte
received and eliminates the need for separate
transmit-empty and receiver-full bits. A status flag
is used to indicate that the I/O operation is com-
plete.
Various data/clock timing relationships may be
chosen (see
