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