PS017609-0803
The Serial Peripheral Interface
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 illustrated in Figures 74 through 76.
