24 bit GPIF II interface?
I'm planning a project using an FX3 communicating with an FPGA on the GPIF II interface. I need to have the SPI port, so I can't use 32 bit mode. The project parameters recently changed, so I'm looking to get as much throughput as possible, so I'd like to use 24 bit mode for a slave fifo like interface. GPIF II designer and some documentation allow 24 bit interfaces, but the documentation on actually using a 24 bit interface is incomplete. Are there an firmware examples available for initializing a 24 bit interface?
Also, if I'm using a Bulk IN, how will the 24 bit data transfer to the PC?
