Division of pulse into multiple base cycles to reduce ripple
Two resolution settings
The resolution can be set equal to one or two system clock cycles.
Two base cycle settings
The base cycle can be set equal to T
Four operating speeds
Four operation clocks (by combination of two resolution settings and two base cycle settings)
