Character Generation
Character generation provides the content of the OSD. The Z90255 supports 14-
pixel (horizontal) by 18-pixel (vertical) character display with 512 character sets.
Character Cell Resolution
Characters are mapped pixel-by-pixel in Character Generation Read-Only
Memory (CGROM).

Figure 12 Character Pixel map in CGROM
Figure 12 is an example of a 512 character set where the character pixel map
represents the first and last characters. It is 14 pixels horizontal and 18 pixels
vertical. Each row in the map is 7 bits long, half the width of the character scan
line.
Even numbered rows in the map correspond to pixels on the left half of the
character scan line; odd rows in the map correspond to pixels on the right half of
the character scan line.
