17. SERIAL PERIPHERAL INTERFACE BUS
The Serial Peripheral Interface (SPI) provides access to a four-wire, full-duplex, serial bus. SPI supports the
connection of multiple slave devices to a master device on the same bus. A separate slave-select signal (NSS) is
used to select a slave device and enable a data transfer between the master and the selected slave. Multiple masters
on the same bus are also supported. Collision detection is provided when two or more masters attempt a data
transfer at the same time. The SPI can operate as either a master or a slave. When the SPI is configured as a
master, the maximum data transfer rate (bits/sec) is one-half the system clock frequency.
When the SPI is configured as a slave, the maximum data transfer rate (bits/sec) for full-duplex operation is 1/10 the
system clock frequency, provided that the master issues SCK, NSS, and the serial input data synchronously with the
system clock. If the master issues SCK, NSS, and the serial input data asynchronously, the maximum data transfer
rate (bits/sec) must be less that 1/10 the system clock frequency. In the special case where the master only wants to
transmit data to the slave and does not need to receive data from the slave (i.e. half-duplex operation), the SPI slave
can receive data at a maximum data transfer rate (bits/sec) of the system clock frequency. This is provided that
the master issues SCK, NSS, and the serial input data synchronously with the system clock.
