While the counter is in an always-on domain (the architecture mandates
this) I don't think that applies to the timers (i.e. the comparators
within a CPU), which are almost certainly not in an always-on domain.
I suspect that this is incorrect, and it will be very painful to debug
if it is...
Thanks,
