26.2 Fixed Duty Cycle Mode
In Fixed Duty Cycle (FDC) mode, every time the accumulator overflows (NCO_overflow), the output is toggled. This provides a 50% duty cycle with a constant frequency, provided that the increment value remains constant.
The FDC frequency can be calculated using Equation 26-2. The FDC frequency is half of the overflow frequency since it takes two overflow events to generate one FDC clock period. For more information, refer to Figure 26-2.
