Hello, I have a question. Regarding waking up the system from LOW POWER mode, I want to use the WKPU but not with a push button as in the example. Instead, I want to use a GPIO port to monitor an external signal. I want to use a rising edge interrupt. I cannot use INT18 because it is connected to a push button and the signal pin is always connected to VCC. Therefore, a rising edge cannot be achieved.
