2.5.22. Single-Ended Strobe Signal Differential Pin Pair Restriction

If you use single-ended external memory interface or PHY Lite strobe signal, such as DQS, leave the remaining positive or negative leg of the differential pin pair as an unused pin.

For example, if you assign a single-ended external memory interface strobe signal to pin function DIFF2B_T_1P, ensure that the other leg of the pair, pin function DIFF2B_T_1N, is left unused.
