COE⁽²⁾
Output
D, O — Digital Output of the C2
Legend: ST = Schmitt Trigger input with CMOS levels, I = Input, O = Output, A = Analog, D = Digital
Note 1: In CM1CON register.
2: In CM2CON register.
3: On USB variants, when USB is enabled, this pin is controlled by the USB module and therefore is not
available as a comparator input.
