I have an I2S component in my design and I've checked the "Clock from terminal" checkbox. Why do I get an error about the source clock (HF1) not being enabled? How is that clock relevant if I'm trying to drive the clock from an external signal?

Have you connected the clock terminal to P5[0] pin? That's the only option you have when enabling this feature. It doesn't mean you can connect to any clock source.

Thanks. I see now that the component datasheet mentions a "dedicated GPIO". Is there some documentation that that dedicated GPIO is P5[0]?

Yes, the device datasheet will tell which pin is used as clk_if. For the first PSoC 6s we launched, it is in P5[0]. You can refer to the Table "Multiple Alternate Functions" in the PSoC 6 datasheet.
