The details of PWM Generator 1 and 2 are not shown for clarity.
On PIC24FJ16MC101 (20-pin) devices, the FLTA1 pin is supported, but requires an external pull-down resistor for
correct functionality.
On PIC24FJ16MC102 (28-pin) devices, the FLTA1 and FLTB1 pins are supported and do not require an external
pull-down resistor.
