Unused pins in PSoC 3 and PSoC 5
If there are some pins unused in design, should they be left unconnected or some points should be taken care?
If the application is a low power application, then place all the unused pins in design and then set drive mode to strong and drive them to zero . By doing so, power consumption will be less. If application is not power critical, then pins can be left to their default state.
