115 / 226 page  8.10.2 Comparator Subsystem (CMPSS) Each CMPSS module includes two comparators, two internal voltage reference DACs (CMPSS DACs), two digital glitch filters, and one ramp generator. There are two inputs, CMPINxP and CMPINxN. Each of these inputs will be internally connected to an ADCIN pin. The CMPINxP pin is always connected to the positive input of the CMPSS comparators. CMPINxN can be used instead of the DAC output to drive the negative comparator inputs. There are two comparators, and therefore two outputs from the CMPSS module, which are connected to the input of a digital filter module before being passed on to the Comparator TRIP crossbar and either PWM modules or directly to a GPIO pin. Figure 8-37 shows the CMPSS connectivity on the 337-ball ZWT and 176-pin PTP packages. Figure 8-38 shows CMPSS connectivity on the 100-pin PZP package.
