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 10.5.
Table 10.4 lists the locations of the additional pulses.
In this example, DADR = H'0207 (B'0000 0010 0000 0111). The output waveform is shown in
figure 10.6. Since CFS = 1 and the value of the upper eight bits is B'0000 0010, the high width of
the base pulse duty cycle is 2/256 × (T).
Since the value of the subsequent six bits is B'0000 01, an additional pulse is output only at the
location of base pulse No. 63 according to table 10.4. Thus, an additional pulse of 1/256 × (T) is to
be added to the base pulse.
