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

Hello Karl,

Apologize for very late response.

We did not have any problems with the double sync in a simple project. The issue is likely related to the specific IO configuration in your project. Could you please share your project ?

Thanks,
