Thanks Paul. But AFAICT, even in that h/w configuration the internal 32k oscillator will be used and so the gptimer will still have a 32k clock source. So I still don't see a use-case where the gptimer would not have a 32k source available. Admittedly, I could be missing one somewhere or I am just plain old wrong ...
