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.
23                 The low voltage threshold range is between 2..21V.
24                 Hysteresis between low and high thresholds can not be lower then 2 and
25                 can not be odd.
27                 If falling threshold results hysteresis to odd value then rising
28                 threshold is automatically subtracted by one.

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