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

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

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