1What: /sys/bus/iio/devices/iio:deviceX/fault_ovuv 2KernelVersion: 5.11 3Contact: linux-iio@vger.kernel.org 4Description: 5 Overvoltage or Undervoltage Input fault. The internal circuitry 6 is protected from excessive voltages applied to the thermocouple 7 cables at FORCE+, FORCE2, RTDIN+ & RTDIN-. This circuitry turn 8 off when the input voltage is negative or greater than VDD. 9 10 Reading returns '1' if input voltage is negative or greater 11 than VDD, otherwise '0'. 12 13What: /sys/bus/iio/devices/iio:deviceX/in_filter_notch_center_frequency 14KernelVersion: 5.11 15Contact: linux-iio@vger.kernel.org 16Description: 17 Notch frequency in Hz for a noise rejection filter. Used i.e for 18 line noise rejection. 19 20 Valid notch filter values are 50 Hz and 60 Hz.
