Control Register Definitions (Continued)
In the LM1253A, an approximation method is used to determine which lines are repeated, and how many times each line is
repeated.
The constant character height mechanism will not decrease the OSD character matrix to less than 18 lines. Each character will
be at least 18 lines high.
Display Window 1 To Display Window 2 Spacing
There is no required vertical spacing between Display Window 1 and Display Window 2, but they should not overlap.
There must be a two character horizontal space between Display Window 1 and Display Window 2 for proper operation of both
windows or undefined results may occur.
Evaluation Character Fonts
The character font of the LM1253A is shown in
Figures 45, 46, 47, 48, 49, 50.
Note that the first two character codes of the two color font (00h and 01h) are reserved for the Window End (WE) and Row End
(RE) codes respectively.
