 I need to measure all width of continuous pulses without stopping the measurement. The pulse frequency is about 10kHz. But the frequency and the duty ratio changes dynamically.

&lt;p&gt;A1:&lt;br /&gt;You cannot store the TIMER value to an arbitrary location in RAM via EasyDMA, but the TIMER value will be present in its CC[x] register (A set location in RAM, see &lt;a title="  Registers  " href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/timer.html?cp=2_1_0_23_4#topic"&gt;Registers&lt;/a&gt;&amp;nbsp;reference for specific adresses) after a TASKS_CAPTURE[x] is triggered.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;A2:&lt;br /&gt;It depends on the PWM frequency. If its frequency is 1/10µs = 100kHz it will be tricky.&amp;nbsp;&lt;/p&gt;
&lt;div&gt;
&lt;div&gt;
&lt;div&gt;&amp;nbsp;&lt;/div&gt;
&lt;/div&gt;
