TFX2 GPIF Long Transfers
Troy Gentry

The purpose of this code is to demonstrate how to implement long transfers in EZUSB FX2 GPIF applications.

What does that mean?  When using the GPIF Transfer Count method the cpu can setup a transfer
of up to 4294967296 transactions (either 8 or 16-bit data bus).  The cpu is still responsible for monitoring and controlling the GPIF, but the data transfers are handled without cpu interaction (typically...although
it is possible for the cpu to interact (via REVCTL.0=1 and REVCTL.1=1)
