Thank you for the response! But what do you mean it can be waked through those clocks? Could you please share an example code how to do it? The reason why I wanted to know if it's possible to run it in light-sleep is because I need to lower the current usage but still receive Manchester encoded mess...

I've noticed in the reference manual for ESP32-C3 that the RMT peripheral now supports two new additional clock sources: RTC20M_CLK and XTAL_CLK.

Can one of those clock source allow RMT to receive/transmit while the chip is in light-sleep mode?
