I have not been able to confirm this from documentation. I need to know what the on/off and termination states of the nRF51822 GPIO pins are when the chip is initially powered up, before the chip has been programmed.
Thank you,
Robin @ TL

Robin,
Upon startup, GPIO pins will be in input mode, but input buffer will be disconnected. Effectively, GPIO will be floating with high impedance.
When waking up from system OFF, GPIO pins will retain previous configured state.
Hello Gritten,
Thank you for the prompt response. As a follow on, how/can this be derived from the documentation? Presumably from the register "reset" values?
Robin...just sent you email
