The Fault Queue requires consecutive fault measurements in order to trigger the alert function. If the temperature

7.5.3.5 Converter Resolution (R1, R0)

The Converter Resolution bits control the resolution of the internal analog-to-digital converter (ADC), thus

allowing the user to maximize efficiency by programming for higher resolution or faster conversion time. Table 10

identifies the Resolution bits and the relationship between resolution and conversion time.
