unused pins in hardware design..
Sorry if this is an obvious question, but couldn't find it in the lit easily, it seems..
We have a 28pin SSOP device (CY8C4245PVI-482) in our design.. we are only using about half the GPIO pins, and wondering what standard practice is concerning the unused/unconnected pins.. should we connect them all to ground, or just let them float?
This is our first PSoC build and we have a very simple circuit.. but want to get the format right before we explore further.
