Power off Mode with no RAM retention doesn't revive controller on interrupt

Hello,

I am trying to reduce the current consumption of BLE nano by sending it to power off mode. If i send it to power off mode, the current is reduced to around 1.8mA. But it does work as predicted when an interrupt wake the controller. To further reduce the current i switched off the ram retention prior going to power off mode. This reduced the current consumption to around 4uA. But the system does not come back in the main loop after wake up, however the current consumption is increased back to 1.8mA.

I am including the code: This code is just for testing purpose. /media/uploads/BilalAhmedShaikh/main.cpp
