| help |
| In normal mode, the resolution of the digital output is selected |
| using the RES0 and RES1 input pins. In configuration mode, the |
| resolution is selected by setting the RES0 and RES1 bits in the |
| control regsiter. When switching between normal mode and configuration |
| mode, there are some schemes to keep them matchs. |
