  Pulses on Do signal during locked state are output to prevent dead zone.
  LD output becomes low when phase is t
WU
 or more. LD output becomes high when phase error 
is t
WL
 or less and continues to be so for three cycles or more.

 > 156.3 ns, fosc = 12.8 MHz)
t
WU 
< 4/fosc (s) (e. g. t
WL
 < 312.5 ns, fosc = 12.8 MHz)
  LD becomes high during the power saving mode (PS = “L”).
