Function
Selects the vertical start position of the display on the screen, VS, as given by the following equation
where H is the horizontal sync pulsewidth. Note that VS increments in multiples of 4 lines from line 0 to line 64.
Selects line 1 pixel height as shown in table 4.
Selects line 2 pixel height as shown in table 5.
Selects line 3 to line 12 pixel height as shown in table 6.
