The vertical display position is automatically centered in the active area at each mode
of VGA ,480-,400-,and 350-line mode . Each mode is selected depending on the polarity of
the synchronous signals described in 4-1(Note1).
In each mode ,the data of TVn is displayed at the top line of the active area. And the
display position will be centered on the screen like the following figure when the period of
vertical synchronous signal,TV,is typical value.
