I am not able to enter into the shutdown mode, i am using the below configuration, I wanted to use the wakeup pin 1 to wakeup form the shutdown mode , but in this it is not going to shutdown mode as the current consumption is at 112uA, what is the correct configuration or steps to do this, in the CubeMX i have configured the pin PA0 as wakeup pin1 int main(void)
