    Hello Jim,

    All these pins can be grounded.

    9,10,11,17 are true NC that they don’t go inside the die, so there is no issue with tying them to GND.

    Pin 8 is used as SCANMODE_EN so grounding it is not an issue.

    Pin 30 is ATP so it is high impedance in mission mode and there is no issue of driving that pin.

    Regards,
