An external pull-down resistor is required for the FLTA1 pin on dsPIC33FJXXMC101 (20-pin) devices.
The FLTA1 pin and the PWM1Lx/PWM1Hx pins are available in dsPIC(16/32)MC10X devices only.
The FLTB1 pin is available in dsPIC(16/32)MC102/104 devices only.
The PWM Fault pins are enabled during any Reset event. Refer to Section 15.2 “PWM Faults” for more
information on the PWM Faults.
Not all pins are available on all devices. Refer to the specific device in the “Pin Diagrams” section for
availability.
This pin is available in dsPIC33FJ32(GP/MC)104 (44-pin) devices only.
