https://devzone.nordicsemi.com/f/nordic-q-a/8401/gzll-device-w-power-managementHi, i try to understand how to use power down modes. But i have a problem in the example gzll_device_w_power_management of nrf24le1 sdk. Before enter register retention in line 75 (EA=0;), we disable all interrupts. My question is, how we will take TICK_ISRen-USTelligent Community 13Tue, 28 Jul 2015 15:50:48 GMThttps://devzone.nordicsemi.com/thread/30530?ContentTypeID=1Tue, 28 Jul 2015 15:50:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:dafb9b62-1b84-4d29-9913-e3f77049126fSusheel Nuguru<p>please accept his answer answer by clicking ✓ mark left to Hung&#39;s answer.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/30529?ContentTypeID=1Tue, 28 Jul 2015 14:11:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4cb6ca6b-93c7-43e1-adc5-9ecbabd2d4c9tass<p>Special thanks Bui</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/30528?ContentTypeID=1Tue, 28 Jul 2015 11:51:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:dc33447e-741d-46c6-b1b1-4ff7143f8739Hung Bui<p>@tass:</p> <p>Setting EA=0 only block interrupts, not blocking them to wake the chip up.
