In both of the above modes the Character matrix, and TV
lines per row can be defined. There is an option of 9, 10,
13 & 16 TV lines per display row, and a Character matrix
(HxV) of 12x9, 12x10, 12x13, or 12x16. Not all
combinations of TV lines per row and maximum display
rows give a sensible OSD display, since there is limited
number of TV scan lines available.
Special Function Register, TXT21 is used to control the
character matrix and lines per row.
