Current Consumption when Input Buffer Disconnected

Current Consumption when Input Buffer Disconnectedhttps://devzone.nordicsemi.com/f/nordic-q-a/52309/current-consumption-when-input-buffer-disconnectedHello, I am looking at the nRF51822 and was wondering if I have the input buffer disconnected, is there a difference in current consumption for that pin if it is not connected vs. connected to ground ?

If you leave some pins floating with default configuration, there will be no difference in power consumption. But there is a good practice to ground unused pins to improve ESD protection.</p><div style="clear:both;"></div>
