Please be aware that PCI-e management on CCOMe-C96 carrier board requires that the add-in card placed on this slot manages the Presence Detect
pins (B81/B48/B31/B17 and A1). More exactly, according to the PCI Express Card Electromechanical Specification v3.0, it is required that these pins
are tied together on the ADD-in Card (at least, it is needed that pin A1 is connected with pin B81 or B48 or B17 or pin B31).
In case that these pins are not tied together on the add-in card, then the carrier board will not acknowledge the presence of the card in the slot, and will
not enable the reference clock (and the add-in card will not work).
