I have a device with a programmable output pulse width for its data ready signal. I need to be able to reliable receive the pulse so I don't miss any interrupts, and I'd like to do that in the minimum possible time so I can send the device a "power down" command as quickly as possible.
I'm seeing interrupt latency as high as 60uS while the nRF52840 is "advertising". Is there any sort of maximum guaranteed latency for GPIOTE pins in "low accuracy" mode?
