| measurement-mode: |
| type: array |
| description: | |
| An array of two integers for configuring the chip measurement mode. |
| |
| The first integer defines the bits 2..0 in the control register. In all |
| cases the internal temperature and supply voltage are measured. In |
| addition the following input measurements are enabled per mode: |
| As per the datasheet, |
| ------------------------------------------- |
| b[2:0] | Mode [2:0] | Mode Description |
| 0 | 0 0 0 | V1, V2, TR2 (Default) |
| 1 | 0 0 1 | V1 – V2, TR2 |
| 2 | 0 1 0 | V1 – V2, V3, V4 |
| 3 | 0 1 1 | TR1, V3, V4 |
| 4 | 1 0 0 | TR1, V3 – V4 |
| 5 | 1 0 1 | TR1, TR2 |
| 6 | 1 1 0 | V1 – V2, V3 – V4 |
| 7 | 1 1 1 | V1, V2, V3, V4 |
| ------------------------------------------- |
| The second integer defines the bits 4..3 in the control register. This |
| allows a subset of the measurements to be enabled: |
| As Per the Datasheet, |
| ------------------------------------------------------------ |
| b[4:3] | Mode [4:3] | Mode Description |
| 0 | 0 0 | Internal Temperature Only (Default) |
| 1 | 0 1 | TR1, V1 or V1 – V2 Only per Mode [2:0] |
| 2 | 1 0 | TR2, V3 or V3 – V4 Only per Mode [2:0] |
| 3 | 1 1 | All Measurements per Mode [2:0] |
| ------------------------------------------------------------ |
| default: [0, 0] |
