| io-channels: |

| description: | |
| ADC IO channel connected to this NTC thermistor. |
| |
| pullup-uv: |
| type: int |
| description: | |
| The pullup voltage microvoltage in the circuit. |
| If not specified, it is assumed that the pullup voltage is VDD. Therefore, |
| the specified ADC IO channel must be configured so that VDD is used as the |
| reference voltage. |

| pullup-ohm: |
| type: int |
| description: | |
| The pullup resistance in the circuit. |
| |
| pulldown-ohm: |
| type: int |
| description: | |
| The pulldown resistance in the circuit. |
| |
| connected-positive: |
| type: boolean |
| description: | |
| Indicates how the thermistor is connected in series with a pull-up and/or |
| a pull-down resistor. If this flag is NOT specified, the thermistor is |
| assumed to be connected-ground, which usually means a pull-down resistance |
| of zero but complex arrangements are possible. |
