nRF52832 is not going to Deep Sleep Mode

Hello,

I am working with nRF52832 and want to put it to sleep and wake it up with a interrupt from a GPIO. I am using a accelerometer LIS3DH to generate the interrupt. I am following the System OFF example from Zephyr Samples. I am using it without retention.

Link to example: https://github.com/zephyrproject-rtos/zephyr/blob/main/samples/boards/nrf/system_off/src/main.c

The device is not going to sleep as I can observe 30mA continuous current consumption. 

Attaching my custom board and code. 

Please verify the code. 

Regards,

Sri
