The datasheet shows that GPIO[53 - 56] are used for UART and SPI so why can't I use SPI when 32-bit GPIF is configured? I did notice on pg 34 of CYUSB3014 FX3 datasheet only UART is listed under the "GPIF II - 33(FX3)..." column.
Yes. As you noticed in the 34th page of data sheet, we can not use these lines for SPI as they are dedicated to UART when you configured GPIF to 32 bit.
