About NC pins in AM35xx

Hello.

Comparing two schematic sources from TI and LogicPD I found that in TI technical reference manual pins N21, N22 marked as not connected while in logicPD schematic these pins are used.

Also, U2 and V1 pins marked as reserved and not connected in LogicPD schematic but in TI technical reference manual this pins must be pulled up via a 10k-Ω resistor.

Any advices?

Thank you.

PS.  Pins regarding ZCN package.

    These terminals are connected to unsupported features in the AM35xx devices.  The current version of the AM35xx data sheet describes the proper connections for these terminals.

    Terminals N21 and N22 should be left unconnected.

    Terminals U2 and V1 should be pulled up via a 10k ohm resistor.
