Background control bits

These bits select the type of background in screen units from none, black-framed, black-on-white, or black-filled

background.

No background : Only character data are output.

Black framing

: If the left- and rightmost columns or the top and bottom lines of a dot matrix are not used, the

displayed character can be framed horizontally, vertically, or diagonally. When the dots on the

rightmost or leftmost column of the dot matrix are used, a frame is displayed in the adjacent

character display areas. Even when the dots on the top and bottom lines of the dot matrix are

used, the lines above and below the dot matrix are not framed. Even if the character size is

changed, the size of black framing is fixed to 1 dot, which is the minimum size.

Black-on-white : A black background is displayed on the rightmost and leftmost positions of the display area

of the character written to the video RAM with 1 extra dot, which is the minimum size, at

both positions.

Black filling

: A black background is displayed outside the character display area, in addition to the black-

on-white background.,
