CONVERTER RESOLUTION (R1/R0)

The Converter Resolution Bits control the resolution of the internal Analog-to-Digital (A/D) converter. This allows

the user to maximize efficiency by programming for higher resolution or faster conversion time. Table 8 identifies

the Resolution Bits and relationship between resolution and conversion time.
