Deep sleep wake from PDM Mic #137

I'm trying to figure out if we can use the newly added PDM Microphone to wake up ESP32 from deep sleep. Can you confirm if this is possible with the V3 of the watch. If yes can you please point to reference documentation. Thanks!

No, it could not. PDM Mic is working only if I2S clock running and sampler running.
