Can all GPIO pins be mapped as a external interupt pin?

[d.kearney]

Hello ,

Easy question, I am using the nRF52832 and am trying to find out if all gpio pins have gpiote functionality? And if so can all gpios be configured as an external interrupt to wake MCU from deep sleep mode?

Thanks

Hi,

You cannot have GPIOTE functionality on more than 8 channels at once, this can be any GPIO however as they are connected through a pin crossbar.

Any gpio can be configured as wake up interrupt.

Best regards,
