https://devzone.nordicsemi.com/f/nordic-q-a/16992/3-time-aligned-pwm-channelsI need 3 time aligned PWM channels (period of all three channels needs to start at the same time) at about 100 Hz with 16 bit resolution on the duty cycle. I also need to trigger some code to run when all three channels are in there off cycle.

The pwm hardware is only present on nRF52. The pwm library frequency is limited to 200kHz and the duty cycle update frequency is limited to maxiumum 100kHz. An overview is on <a href="https://devzone.nordicsemi.com/question/97895/sdk12-app_pwm/">this thread.</a></p><div style="clear:both;"></div>
