Since the value of the following six bits is B’0000 01, the additional pulse is output at the position
of basic pulse No. 63 as shown in table 10.4. Only 1/256
the basic pulse.
Note that the case of CFS = 0 (basic cycle = resolution (T)
of the basic pulse is determined by the upper six bits, and the position of the additional pulse is
determined by the following eight bits.
