I try to use st25r3911 and try to achieve low power consumption.
The code configures interrupts: gpio_pin_interrupt_configure_dt(&irq_gpio, GPIO_INT_EDGE_TO_ACTIVE);
But this string add about 15 uA to power consumption.
Can i reduce this value?

Hello,
This current increase is expected when using GPIOTE IN channels:
The solution is to use PORT events instead. This can be achieved by using the 'sense-edge-mask' property in your GPIO node in your device tree.
&gpio0 {
/* Use PORT events for all pins by default */
sense-edge-mask = <0xffffffff>;
};
Best regards,
