In this example, DADR = H'0207 (B'0000 0010 0000 0111). The output waveform is shown in
figure 11.6. 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
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 11.4. Thus, an additional pulse of 1/256
be added to the base pulse.
However, when CFS = 0 (base cycle = resolution (T)
determined by the upper six bits and the locations of the additional pulses by the subsequent eight
bits with a method similar to as above.
