Web27 jan. 2015 · resistors when pushbutton or keypad devices are connected. The pull-ups and pull-downs are enabled separately using the CNPUEx and the CNPDx registers, which contain the control bits for each of the pins. Setting any of the control bits enables the weak pull-ups and/or pull-downs for the corresponding pins. The CNCONx registers provide … Web16 jan. 2024 · While running, the current measured is approx 110µA (as expected). During deep sleep, with the old code (in the question, that sets up a weak pull-up), the current falls to ~50µA (so the pull-up resistor value is in the 30k range). With the suggested code here, it …
