Gen3 1 Hz Square Wave during sleep?

I have a Sharp Memory LCD that requires a 1 HZ square wave pulse to keep the pixels charged and to extend the lifespan of the LCD.

Is there a low power way to have the NRF chip on the Argon provide a 1HZ pulse even when in one of the sleep modes?

I just wanted to ask before looking for a low power dedicated chip to produce this square wave when the Argon is in a low power sleep mode.

I think it may have a way of doing this but would probably require some custom code to enable it.

Are you looking at the STOP sleep?

I’m not an expert, but if it were me I’d start with trying it after commenting out the line:
