	  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.
