W/S
Corrects the screen origin during inverse display. Normally set IV = 1.
The most effective way to display characters in inverse video is to use a unique function of the
S1D13700 that allows the text screen and graphics back-layered screen to be exclusive OR’d.
However, because the character origin is at the upper-left corner of the screen when characters
are mapped on the screen by the S1D13700, the uppermost line and leftmost column on the
display screen do not have dots to draw the outline of characters, thus making the displayed
characters illegible. Therefore, the S1D13700 uses the IV specification and horizontal direction
dot scroll function (HDOTSCR command) to shift the origin of the text screen for correction
with respect to the graphics back-layered screen, allowing characters to be displayed in inverse
video anywhere on the screen. For details, see Section 4.1.7 “Scrolling” on page 65.
