Vertical reset in VD/HD sync mode
The phase of EXTVD should be input as shown in the diagram below against the first equivalent pulse during
vertical blanking period.
(Take care as the following conditions might not be satisfied depending on the phase setting of INTf
H
if the
phases are locked when the falling phase shifts a lot between EXTf
H
and INTf

.)
