Generate 32768 hz signal on a GPIO

[Florin]

Hi,

Sorry for the noob question: I would like to generate a signal on a GPIO pin that beats at exactly at 32768 Hz. Is it possible to use the RTC having prescaler set to 0 and CC set to 1?

Thank you! florin

Sure. I want to control another chip, a SI4703 that requires a 32kHz clock. I don't know if it's possible to share the same XTAL with the nRF51 though therefore an option is to generate this clock signal separately.
