    PSOC6 GPIO double-sync / glitch filter problems

    KaAs_973901

      Hello, I've taken a project from a PSOC 5LP and moved it over to the PSOC 6 platform in order to create a WiFi enabled version. The signal source is somewhat noisy and a glitch filter or double-syncing the input pin had resolved filtering out small 8-24ns pulses.

       

      Attempting to use the same option now, it appears the glitch filter component has been removed and selecting double-sync on a digital input results in:

       

      sta.M0017: Unsupported: InSyncNeeded

       

      and subsequently has no affect in the application.

       

      I'm currently working around the issue by clocking a DFF with a slower clock, but am looking to understand why the double-sync on the pin is not working.

       

      Thanks,
      Karl
