11.4.11.2.2 Reference Input Selection

The feedback input is selected from a sixteen input multiplexer as shown in Figure 11-5. The value for the reference pin will be taken only from the output of that particular selected pin. For example, if the selected pin is the pin out of PWM, the PWM out is taken as the reference input; this can also be manually updated by setting LAT of the selected pin to 0/1.
