This is for the nRF51822.
I have done some tests where I configure a pin as input with pull up enabled and then reconfigure the pin for an adc measurement with 1/3 prescaler with band gap reference.
It looks like the pull up is enabled when the adc measurement is done (which is very helpful for my use case), but I can't find information about this in the datasheet and previous questions on devzone have comments that indicate that it is not enabled in adc mode.
Has anyone else seen this behaviour and can I trust that it works the same in different revisions of the silicon?
