DA14531 Hibernation not working issue

Hi Team,

I am using the DA14531 IC WLCSP package without any external memory to support it, I tried to make the system into hibernation mode to reduce the power consumption of my system but the system is not getting into hibernation mode.

I tried RAM hibernation later I will change it to OTP hibernation by referring to the Renesas hibernation mode documents, but it is not getting into hibernation mode system by referring to power consumption I'm saying this is the system is consuming around 700uA consumption. The wakeup mechanism is through pin P0_1, this is configured as input pullup.

Please provide any suggestions to fix this issue in DA14531.

Let me know if you need any further information
