Power-on Reset supply voltage
.
.
Power-on reset is performed when the supply voltage V
under 0.05 V and kept the level for at least 20ms.
Latch data is retained when the V

.
This data controls the phase comparator dead zone.
(DZA < DZB)
This is the IC test mode switching data. The user does not need to be
concerned about this data.
Normally, the test pins must be either at V
