https://devzone.nordicsemi.com/f/nordic-q-a/48158/nrf52840-dk-spis-cannot-use-p0-22-and-p0-23Hello. I would like to use the SPIS module on the nRF52840 DK. I configured it by following the examples given by Nordic. When I use pins P0.14 (nCS), P0.15 (SCK), P0.16 (MISO) and P0.17 (MOSI) for the SPI, everything functions well.
