I'm designing a board for using the FLIR Lepton 2.0 LWIF camera (datasheet at https://www.flir.com/globalassets/imported-assets/document/lepton-engineering-datasheet---without-radiometry.pdf), and several of the pins are marked as unused. One is labeled as "No Connection" and four others as "RESERVED" (which is due to the fact that the Lepton 2.5, which uses the same case, has additional I/O pins). Given that I cannot set (and therefore do not know) the input/output state of these pins, and that they are likely disconnected internally, what should I do with them? My instinct is to connect them to ground through a pull-down resistor, but this may not be correct.
(As a side note, I'm using the Molex 105028-1001 socket for mounting this component.)
