Pins for general use in FTPC of CY3271

Version 1
    Question: What pins on the PC Dongle header of CY3271 are available for general use?



    The pins FTPC0[2:6] and the nPASSIVE/ACTIVE can be used for general purpose applications. The purpose of the nPASSIVE/ACTIVE pin is basically to identify if any other daughter card is connected to the FTPC by checking if Vcc is available at this pin. Hence this pin can also be used for general purpose applications.  Please refer the Female expansion port pins in the attached PC Dongle header schematics to locate the pins are coming out for general use.
