   5 Description:
   6                 Program sensor type for threshold detector inputs.
   7                 Could be either "GND-Open" or "Supply-Open" mode. Y is a
   8                 threshold detector input channel. Channels 0..7, 8..15, 16..23
   9                 and 24..31 has common sensor types.

  15 Description:
  16                 Channel Y low voltage threshold. If sensor input voltage goes lower then
  17                 this value then the threshold falling event is pushed.
  18                 Depending on in_voltageY_sensing_mode the low voltage threshold
  19                 is separately set for "GND-Open" and "Supply-Open" modes.
  20                 Channels 0..31 have common low threshold values, but could have different
  21                 sensing_modes.
  22                 The low voltage threshold range is between 2..21V.
  23                 Hysteresis between low and high thresholds can not be lower then 2 and
  24                 can not be odd.
  25                 If falling threshold results hysteresis to odd value then rising
  26                 threshold is automatically subtracted by one.

  32 Description:
  33                 Channel Y high voltage threshold. If sensor input voltage goes higher then
  34                 this value then the threshold rising event is pushed.
  35                 Depending on in_voltageY_sensing_mode the high voltage threshold
  36                 is separately set for "GND-Open" and "Supply-Open" modes.
  37                 Channels 0..31 have common high threshold values, but could have different
  38                 sensing_modes.
  39                 The high voltage threshold range is between 3..22V.
  40                 Hysteresis between low and high thresholds can not be lower then 2 and
  41                 can not be odd.
  42                 If rising threshold results hysteresis to odd value then falling
  43                 threshold is automatically appended by one.
