The best way I know is using pins as Bus and checking the option Contigous, PSoC will try to route the pins one after other; for example one bus of output pins for 7 switches, creator will arrange pins from P1.1 to P.7
Thanks for the reply.
Guess what I just found? I just read this in the PSoC Creator v 3.3 Release Notes :
Guided Pin Selection
This feature helps the user make optimal decisions when choosing physical pins in the Pins DWR editor for PSoC 4 devices. Ideal selections are highlighted in green while legal, but resource-consuming, options in yellow.
I remember seeing this happed (the GREEN pins) also when using the DWR editor for my PSoC 5LP.
