Admittedly, I haven't done the research on this, but for many microcontrollers, 40MHz on the SPI exceeds the limits. Perhaps a default value of something lower that is more clearly configurable, or perhaps the accompanying example application can pass in a lower default value that will be more compatible across platforms.
