WebMar 28, 2024 · The first cell is the IRQ number, the second cell is used to specify one of the supported IRQ types: IRQ_TYPE_EDGE_RISING = low-to-high edge triggered, IRQ_TYPE_EDGE_FALLING = high-to-low edge triggered, IRQ_TYPE_LEVEL_HIGH = active high level-sensitive, IRQ_TYPE_LEVEL_LOW = active low level-sensitive. WebIRQ_FALLING, handler = callback) We set pin 0 to trigger only on a falling edge of the input (when it goes from high to low), and set pin 2 to trigger on both a rising and falling edge. After entering this code you can apply high and low voltages to pins 0 and 2 to see the interrupt being executed. WebAdd SSI{0,1,2,3} nodes to RZ/G2L SoC DTSI.
