Are SPI pins tristated until the start of configuring FPGA in AN84868? If no configration data are sent to FX3, will the spi pins stay tristated?

Hi,

I can't comment exactly about the state of MOSI and MISO pins. I mostly found that MOSI is in Logic 0 state but MISO is tri-stated.

You can check it but putting "while(1)" loop after the "CyU3PSpiInit()".

Thanks & Regards
