The FX3API Guide says when I de intialize the SPI, the SPI is disabled and the power to the SPI module is turned off. Are the SPI pins in tri-state when this is done?

The module will be powered-down but the lines will still be SPI lines (they may not be tri-stated in the true meaning of the term). Configuring it as GPIO and making it an input would be better way to make sure it is tri-stated.
