STA680

Digital I/O and memory interfaces

5.5

Serial peripheral interfaces (SPI)

The STA680 provides three serial peripheral interfaces:



SPI1 is intended for communicating with the Host Microcontroller (slave);



SPI2 interfaces the STA680 to the external flash memory (master);



SPI3 - Reserved.

Figure 11 shows the timing diagrams and waveform for the three SPI interfaces.
