Note 1:
An external pull-down resistor is required for the FLTA1 pin in dsPIC33FJXXMC101 (20-pin) devices.
2:
The FLTA1 pin and the PWM1Lx/PWM1Hx pins are available in dsPIC(16/32)MC10X devices only.
3:
The FLTB1 pin is available in dsPIC(16/32)MC102/104 devices only.
4:
The PWM Fault pins are enabled during any Reset event. Refer to
for more
information on the PWM Faults.
5:
Not all pins are available on all devices. Refer to the specific device in the
section for
availability.
6:
These pins are available in dsPIC33FJ32(GP/MC)104 (44-pin) devices only.
