4.7 SPI Slave Interface
The CleO35 has a SPI slave interface that supports single and dual (2 data lines) SPI data transfer
modes. This interface supports both 5V, 3.3V and user defined output levels. The user defined interface
levels must be between 3V (min) to 5.5V (max). The power selectionjumper is through CN10.
