I am attaching my project.</p> <p>In that I have connected pin P27 and P26 in dev kit. Pin 26 I am generating pulse and interrupt will be generated in pin 27. In pin 28 GPIO interrupt I am clearing timer but still I am getting timer expire interrupt.</p> <p></p> <p><a href="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/uart_5F00_Nordic_5F00_Timer.zip">devzone.nordicsemi.com/.../uart_5F00_Nordic_5F00_Timer.zip</a></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/237066?ContentTypeID=1Fri, 28 Feb 2020 09:18:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:277f9bac-7a2c-4b21-b067-fc1a2cd58100ovrebekk<p>Hi</p> <p>There is no need to stop the timer before clearing it, no.

Can you try simply clearing the timer without disabling and enabling it?</p> <p>Best regards<br />Torbjørn</p><div style="clear:both;"></div>
