Bitstream Generation...

This is for a General Purpose Input / Output (GPIO) 1.0, when I try to configure it like this:

I'm able to reproduce this, I see the warning. Looks like Sync mode for PSoC6 devices is unsupported. I will pass this query to internal software team to evalutate this.

You can use the workaround mentioned in this thread of using a DFF: PSOC6 GPIO double-sync / glitch filter problems
