    PSoC 4 GPIO termination

    NaJa_4363881

      Hello,

       

      I am designing a prototype board with PSoC 4 WLCSP package device (CY8C4014FNI-421AT). I went through the sample schematics for CY8CKIT-040 and also checked the Technical Reference manual for the device family, but I am not sure on how to terminate unused GPIO pins such as the Trigger Input pin (In my case P 0.2).

       

      For now, I have simply left the unused GPIO pins suspended, but I am not sure about these Trigger input pins that can also be used as CDS sense or as shield pins that are connected to AMUXBUS A or B.

       

      It will be great if someone could advise me regarding this concern.

       

      Thanks and Regards,
