NA: HANG ON! GPIF and Serial interface ports are different?

Looking at the block diagram on 3/39 pg of the CYUSB3014 datasheet-

GPIF II block is shown separate from the serial interfaces blocks! And somewhere else in the UG of the GPIF II designer I read about the reduction in number of pins based on the whether a SPI/I2C or other interfaces have been connected to the FX3.

Also, when I check the check box for SPI in the Designer Tool, there wasn't any evident change in the schematics on the screen. ... what could that mean?
