PPS Description
Legend: CMOS = CMOS compatible input or output Analog = Analog input P = Power
ST = Schmitt Trigger input with CMOS levels O = Output I = Input
PPS = Peripheral Pin Select
Note 1: An external pull-down resistor is required for the FLTA1
pin on PIC24FJ16MC101 (20-pin) devices.
2: The FLTB1
pin is available in PIC24FJ(16/32)MC102/104 devices only.
3: The PWM Fault pins are enabled during any reset event. Refer to Section 15.2 “PWM Faults” for more
information on the PWM faults.
4: This pin is available in PIC24FJ(16/32)MC104 devices only.
5: Not all pins are available on all devices. Refer to the specific device in the “Pin Diagrams” section for
availability.
