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 9.4. Thus, an additional pulse of 1/256 × (T) is to
be added to the base pulse.

However, when CFS = 0 (base cycle = resolution (T) × 64), the duty cycle of the base pulse is
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.
