An example of setting CFS to 1 (basic cycle = resolution (T)
output) is shown as an additional pulse. When CFS is set to 1, the duty ratio of the basic pulse is
determined by the upper eight bits (DA13 to DA6) in DADR, and the position of the additional
pulse is determined by the following six bits (DA5 to DA0) as shown in figure 8.5.
Tables 8.4 to 8.6 show the position of the additional pulse.
Here, the case of DADR = H'0207 (B'0000 0010 0000 0111) is considered. Figure 8.6 shows an
output waveform. Because CFS = 1 and the value of upper eight bits is B'0000 0010, the duty ratio
of the basic pulse is 2/256
