PS019921-0308
Figure 21. SPI Configured as a Master in a Single Master, Single Slave System
The Serial Peripheral Interface is a synchronous interface allowing several SPI-type
devices to be interconnected. SPI-compatible devices include EEPROMs, Analog-to-
Digital Converters, and ISDN devices. Features of the SPI include:
•
•
•
•
•
The SPI may be configured as either a Master (in single or multi-master systems) or a
Slave as displayed in
To Slave’s SS Pin
Full-duplex, synchronous, character-oriented communication
Four-wire interface
Data transfers rates up to a maximum of one-half the system clock frequency
