TWIM instance crashing on the reconfigured P0.9 and P0.10 pinshttps://devzone.nordicsemi.com/f/nordic-q-a/67253/twim-instance-crashing-on-the-reconfigured-p0-9-and-p0-10-pinsHi, I&#39;m using nrf52840 on a custom board and have a sensor connected over the pins P0.9 and P0.10 which are NFC pins that have been converted to GPIO by using macro (CONFIG_NFCT_PINS_AS_GPIOS). Both pins work properly as digital output pins, buten-USTelligent Community 13Thu, 15 Oct 2020 15:21:24 GMTRE: TWIM instance crashing on the reconfigured P0.9 and P0.10 pinshttps://devzone.nordicsemi.com/thread/275162?ContentTypeID=1Thu, 15 Oct 2020 15:21:24 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fd5d5dda-6574-4b33-aac9-773e24ccc2ceKenneth<p>I suspect that there may be capacitance on those pins that prevent the pins to be pulled-up as expected.&nbsp;Are you using internal or external pull-up resistors? If internal, then make sure to have some delay between enabling and before execute transfer. Maybe look at a logic analyzer trace when working and failing.</p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>
