However, fans and output_pin devices may be optionally configured to use `hardware_pwm: True`, in which case the micro-controller must support hardware PWM on the pin (otherwise, Klipper will report a "Not a valid PWM pin" -error). Note that hardware PWM is currently only supported on the avr, -atsam, samd21, and linux micro-controllers. +error). IRQ pins (or Interrupt pins): Klipper does not use hardware interrupts on IO pins, so it is never necessary to wire a device to one of these
