4.3 mCMP2_Output_EnblDsbl(state)
4.4 mCMP1_Output_EnblDsbl(state)
This peripheral library module:
· Provides two ranges of output voltage, each with 16 distinct levels.
· Can come from either VDD and VSS, or the external VREF+ and VREF-.
Note: The settling time of the comparator voltage reference must be considered when changing the CVREF output.
Library routine parameters can be constructed using either AND based mask or AND_OR based mask setting. For more information on these masks, see 16-bit Peripheral Libraries.
Example of Use ( AND_OR mask )
