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 ...

Cheers
Jon
