https://devzone.nordicsemi.com/f/nordic-q-a/44740/nrf52840-qspi-dpmHello, Recently I&#39;m working on the project that utilizes the nRF chip and the external memory MX25R3235F. The SDK is 14.2. I&#39;m trying to configure the peripheral and the external flash to enter the DPM to achieve the lowest possible current.
