What's the delay from setting the Start / Stop task in an RTC module to when the RTC actually starts or stops? Is it less than 1 clock cycle on the CPU (15ns)? More than one...
Hi, I am using the nrf52 dk to sample two analog inputs through PPI.
My question is if I can use different bit resolutions for each analog input?
