Next questions:

1.  Can we do like that  :Power  0.9 V -> pin1 VDDIO  [ chip N]  pin42 VDDIO -> pin1 VDDIO [chip N+1], without connection on PCB between pin1 and pin 42 on the same  ASIC

2. VDDPLL is pin 14 ; pin 29 is  NC(not connected). Can we use  pin 29 for VDDPLL to the next ASIC

3. The NC (not connected ) pins do they have some function ( i.e. Inputs, Outputs etc.)
