Multiple GPIF Waveforms for the EZ-USB FX1/FX2/FX2LP

Version 1
    Question: Can I use more than four GPIF waveforms with the EZ-USB FX1/FX2/FX2LP?



    Yes. However, only four are available at a time and the firmware would be responsible for loading up a new set, prior to activating the GPIF, each time a new set is required. Loading a waveform may consist of simply altering one or more bytes within one or more waveforms or may consist of completely replacing one or more entire waveforms.
