I need to be able to go into stop mode (low power) and still count pulses coming in from an external source.

I set up TIM1 (also tried TIM2) to use an external clock source and it doesn't continue to count when I go into stop mode.

Is this possible?, to count pulses from an external clock source when in stop mode?

If you have resolved this I would be interested as I need to do this in the next few weeks. If you haven't I intend to use external interrupts which are listed as wake-sources from stop mode (I have used successfully in the past). I will update as I make progress.
