PWM Tolerance

[WesC]

nRF52840

NCS V 2.2.0

Using the NRFX drivers natively trying to set the PWM to 333uS.

over 20 different units i am seeing this vary form 326 to 335

what is the expected accuracy (tolerance) of the PWM output.

Is there an example of the PWM in NCS that uses the NRFX drivers and not the Zephyr Drivers

I found this example, but haven't had a chance to test it.  This is very similar to my code.  I will run tests, but can you do similar to see how well it holds tolerance to 333us.ncs-nrfx-pwm-simple-example-master.zip

would this be the suggested way to use the NRFX drivers for the PWM.

If i use Zephyr and use something like PWM-LEDs for some other reason work better?

finally how do i determine if i am running from the HFCLK?
