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.
