HI Sirs,

Sorry to bother you.

Because TUSB7340 will put ont CPU board, so we don't have some control pin from PCIE

We would like to know

1. Could we NC wake & clkreq pin if we don't need?

2. Could we tied together between PERST and GRST?
3. If we only use three USB, could we NC the last USB?

4. All control signal are 3.3v?

Thanks!!
