    Hi

    I am trying to interface an External ADC ( bcoz of range constrains 10Volts)
    which is TI device TLC2578.

    I have correctly interfaced host and device in SPI as mentioned in data sheet.

    I need some input about EOC/INT pin which currently I left it Open.

    My SPI output at SDO (from ADC device) buffer always reads 0xFF

    somebody please clarify how to use this pin.

    Thanks
