The FX3 support 32 bit GPIF II interface.we are using GPIF Designer 1.0 to Draw interface and state machine diagram.in interface there are only 8,16,24,32 selection for GPIF data bus width.but i need 12 GPIF data bus.please help for selection 12 Bit GPIF data bus.
12 Bit interface is not possible with GPIF. You have to use 16 Bit GPIF. The extra 4 bits need to be removed either in Fx3 or in the host application. If it is done in FX3, the throughput will be afftected. So we recommend to do it in the host application.
