nrf5340 zephyr CONFIG_SPI=y causes increased power consumptionhttps://devzone.nordicsemi.com/f/nordic-q-a/106204/nrf5340-zephyr-config_spi-y-causes-increased-power-consumptionHello, I was investigating some sleep power consumption issues and came across CONFIG_SPI=y causing the nrf5340&#39;s sleep current increasing. I was testing this on the nrf7002 DK with code that consisted solely of a infinite loop of __WFI().

Try disabling the SPI and set <a href="https://infocenter.nordicsemi.com/topic/ps_nrf52840/gpio.html?cp=5_0_0_5_8_1_9#register.PIN_CNF-0-31">PIN_CNF</a>[n] to it&#39;s default value of 2, where n is the pin number for SCLK, CS, MISO, and MOSI.</p> <p>regards</p> <p>Jared</p><div style="clear:both;"></div>
