&lt;p&gt;I have also a problem about the comparator. The comparator does not compare correctly. The detail can be seen&lt;/p&gt;
&lt;p&gt;in the website below. Could you give me some advice? Thanks&amp;nbsp;very much.&lt;/p&gt;

&lt;p&gt;The value of the RESULT register can only be trusted after the READY event has fired. In this state the COMP will fire the interrupts according to its configured boundaries, ie when the signal crosses any of the boundaries.&lt;/p&gt;
&lt;p&gt;You can also trigger the SAMPLE task to get the immediate value of the COMP(above or below).&amp;nbsp;&lt;/p&gt;
&lt;p&gt;You should read the PANs related to the COMP peripheral:&amp;nbsp;&lt;a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.Rev2.errata/dita/errata/nRF52832/Rev2/latest/anomaly_832_12.html?cp=2_1_1_0_1_0"&gt;[12] COMP: Reference ladder is not correctly calibrated&lt;/a&gt;,&amp;nbsp;&lt;a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.Rev2.errata/dita/errata/nRF52832/Rev2/latest/anomaly_832_84.html?cp=2_1_1_0_1_22"&gt;[84] COMP: ISOURCE not functional&lt;/a&gt;, and&amp;nbsp;&lt;a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.Rev2.errata/dita/errata/nRF52832/Rev2/latest/anomaly_832_113.html?cp=2_1_1_0_1_32"&gt;[113] COMP: Single-ended mode with external reference is not functional&lt;/a&gt;.&lt;/p&gt;
&lt;p&gt;Cheers,&lt;/p&gt;
