| description: BUSY pin. |
| |
| The BUSY pin of SSD16XX is active high. |
| If connected directly the MCU pin should be configured |
| as active high. |

| description: Temperature Sensor Selection Value |
| |
| Display controller can have integrated temperature sensor or |
| an external temperature sensor is connected to the controller. |
| The value selects which sensor should be used. |

| description: | |
| Child nodes describe refresh profiles. Each refresh profile |
| specifies a set of voltages used to drive the refresh |
| cycle. Refresh profiles are optional and are used to override |
| defaults loaded from the controllers OTP memory. |
| |
| Partial refresh will be disabled unless a partial refresh profile |
| has been specified. That profile may be empty to use the defaults |
| loaded from OTP if supported by the device. |
| |
| The driver typically looks for the following child nodes: |
| |
| - 'full' - Normal / full refresh. |
| - 'partial' - Partial refresh. |
