fx3_flagc_n and fx3_flagd_n of glip_cypressfx3_toplevel #63

I was wondering about the flagc and flagd inputs in the FX3 toplevel entry: The CYUSB301X has only flaga and flagb described in its CYUSB3014 manual. Which pins are these?

That manual only gives a very rough overview of the GPIF II and the configuration of the FIFO interface. For a more detailed description please have a look at the Applicatino Notes AN65974. These notes also provide some design examples and describe the different flags.
For our toplevel we use flags a and c as full and empty flags respectively, and flags b and d as partial full/empty flags.
