An example of the additional pulses when CFS = 1 (base cycle = resolution (T) × 256) and OS = 1
(inverted PWM output) is described below. When CFS = 1, the upper eight bits (DA13 to DA6) in
DADR determine the duty cycle of the base pulse while the subsequent six bits (DA5 to DA0)
determine the locations of the additional pulses as shown in figure 9.6.
Table 9.6 lists the locations of the additional pulses.
