7.3.2. Window Detector In Differential Mode
Figure 7.17 shows two example window comparisons for right-justified, differential data, with
ADC2LTH:ADC2LTL = 0x0040 (+64d) and ADC2GTH:ADC2GTH = 0xFFFF (-1d). In differential mode, the
measurable voltage between the input pins is between -VREF and VREF*(511/512). Output codes are rep-
resented as 10-bit 2’s complement signed integers. In the left example, an AD2WINT interrupt will be gen-
erated if the ADC2 conversion word (ADC2H:ADC2L) is within the range defined by ADC2GTH:ADC2GTL
and ADC2LTH:ADC2LTL (if 0xFFFF (-1d) < ADC2H:ADC2L < 0x0040 (64d)). In the right example, an
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 < 0xFFFF (-1d) or ADC2H:ADC2L > 0x0040 (+64d)).
Figure 7.18 shows an example using left-justified data with the same comparison values.
