Configuration of FX2/FX2LP to GPIF Mode
How do I configure the FX2 to go into GPIF Mode?
To configure the pins for GPIF mode, the IFCFG[1:0] bits in the IFCONFIG register must be set to 10.
For more information about GPIF please read through the GPIF chapter in the FX2 Technical Reference Manual. In addition, please refer to the application note, EZ-USB® FX2LP™ GPIF Design Guide - AN66806.
