    sdxc sdcard -fx3s

    geethadiwakargeetha_2778001

      hi,

      i wanted to interface sdxc sdcard to s0 port of fx3s

      i got know that fx3 needs an external regulator to swich from 3.3v to 1.8 IO supply (so port)

      and i have gone through cypress community regarding FX3S- Schematic of USB RAID ON  CHIP USB DONGLE

       

      in which ,

      they are using gpio control on regulator.

      they are using GPIO_16(DQ12) and respective software code as

      initparams.lowvoltage=cytrue;

      initparams.voltageswgpio=VSEL_S0_GPIO;

       

      My question is

      1)is it compulsory to use specific gpio (GPIO_16)?

      2)can i use any other gpio?

       

      thank you...

      if any user manual or document is there,please provide me.
