If I configure SPI interface as a 3-pin SPI for data transmission between DSP and FPGA in our system, can I then use GPIO28/SPISCSC0 and GPIO29/SPISCS1 as GPIO since not used in 3-pin configuration. I had hoped that I could set as reserved in this mode and then use as GPIO. We are going to experiment with this but thought I would ask the question in parallel. We are considering using SPI CLK and SPI DOUT to pass configuration data to FPGA and do not plan to use DIN but would like to use GPIO28 and GPIO29 as GPIO.
Thanks,
James
