How to set nRF24LE1 into power saving register retention mode with timers off with clock source from XOSC32K ? I need the command / code to do this.

Pin wake up problem is solved. Thank you for your support.

Are you sure that the input pin is low when you try to go to sleep?

If the pin is high you won't be able to go to sleep, and the current consumption will stay high.

But when I set this WUOPC0 register the current consumption increases to 1.2mA (milliAmperes) where as in register retention mode it needs to consume between 2-87uA (microAmperes).

Hi Sriranjan

0x02 translates to 00000010 binary, which means that WUOPC0(1) is set. For the nRF24LE1-Q24 this translates to P0.1.

In other words you will enable wakeup on P0.1 when you get a low to high transition on the pin.

Best regards
