7.3.1. Window Detector In Single-Ended Mode
Figure 7.15 shows two example window comparisons for right-justified, single-ended data, with
ADC2LTH:ADC2LTL = 0x0080 (128d) and ADC2GTH:ADC2GTL = 0x0040 (64d). In single-ended mode,
the input voltage can range from ‘0’ to VREF * (1023/1024) with respect to AGND, and is represented by a
10-bit unsigned integer value. In the left example, an AD2WINT interrupt will be generated if the ADC2
conversion word (ADC2H:ADC2L) is within the range defined by ADC2GTH:ADC2GTL and
ADC2LTH:ADC2LTL (if 0x0040 < ADC2H:ADC2L < 0x0080). In the right example, and AD2WINT interrupt
will be generated if the ADC2 conversion word is outside of the range defined by the ADC2GT and
ADC2LT registers (if ADC2H:ADC2L < 0x0040 or ADC2H:ADC2L > 0x0080). Figure 7.16 shows an exam-
ple using left-justified data with the same comparison values.
