Thanks again!

One more question:

I need some additional Single-ended I/O's, because i've already used HSMC_D0 - HSMC_D19. I think it should be possible to use only one signal line of a differential I/O pair like e.g. HSMC_TX_p4/HSMC_TX_n4. But what should i do with the other signal line of the pair? Nothing? Pull-up/down?
