I set it on Pinwake up but it is consuming 1.2mA after I configure the WUOPC0 register.If I dont enable this register then power consumption is 0.002mA but if I configure pin wake up the current consumption goes to 1.2mA.Here is my threadhttps://devzone.nordicsemi.com/f/nordic-q-a/38811/problem-with-nrf24le1-it-is-consuming-1-2ma-current-in-register-retention-mode

Hi Sriranjan,

Please create a new case with more information about your set-up.

Have you managed to test with putting the chip to register retention mode and wake up from normal GPIO pin (instead of analog comparator)

Can some one tell me how to wake up from register retention mode using analog comparator, because I used the above code Bui but could no get it working. Could you please provide the complete code for register retention with analog comparator such that after it wakes up it does some task and goes back to sleep with waking up happening by analog comparator method..

What exactly happens when you test the code ? Did the chip wake up ? Or just stay in PWRDWN=0x04; ?

The issue I was mentioned has the symptom that the device keep resetting even without correct voltage on the analog input.

is there a revision planned or a batch that do not have the bug ?

Hi robotox,

Please try to use Memory retention, timers on mode PWRDWN = 0x04; to check if that help. We found that it was a bug with our chip when you use analog comparator it may mess up with the brownout reset. The issue doesn't happens with the OTP chip.

This code worked for me:

hal_ancmp_set_input_channel(8);//P1.0
hal_ancmp_set_ref_voltage_scale(0x01);//50%
hal_ancmp_set_reference(0);
hal_ancmp_enable(true);
PWRDWN=0x04;
