20.4.3.1 Static Operating Mode

The Static Operating mode will output a fixed DC voltage as defined by DACDAT. Repeated writes will reset the timers and may prevent the DAC from reaching the other filter modes. It is not recommended to repeatedly write the same DACDAT value, as it incurs transients on the output when filters are switched. In Static mode, the filters operate in the order of Transition, Fast and Steady-State modes, as defined by Table 20-9.
