Support Question of the Week: How do I use the API Software for the Cheetah SPI Host Adapter to Filter Data from an SPI Slave Device?

We are using the CheetahTM SPI Host Adapter with an SPI slave device. This slave device sends FF bytes on MISO as long as it is busy (somewhat similar to  the clock-stretch for I2C), and if it is ready a first byte != FF byte is sent at mark 4. From then on, the data is the valid payload of interest that we want at read-data. The problem we h...
