Actually it doesn't reset. It just so happened that the external frequency matched the readout interval so it would overflow each time

OMG! so simple! I took that code from another post here on devzone....

Wasted 3 hours on this.

Thanks for the prompt response.

One additional question: capturing the counter seems to reset it to 0 which is fine. Is there a way to keep it counting?

Hi,

Try:

NRF_TIMER2->TASKS_CAPTURE[0] = 1;

Here is a similar case: Capture timer value.
