Display Modes
The display section has two distinct modes with different features available in each. The two modes are:
TXT:-
This is the display configured as the WST mode with additional serial and global attributes to
enable the same functionality as the SAA5497 (ETT) device.The display is configured as a
fixed 25 rows with 40 characters per row.
CC:-
This is the display configured as the US Closed Caption mode with the same functionality as
the PC83C771 device. The display is configured as a maximum of 16 rows with a maximum of
48 characters per row.
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 and memory mapped registers are used to control the mode selection.
Throughout this section, the features will be described, and there function in each mode given. If the feature is
different in either mode then this is stated.
