Tentative Device Specification
TDA935X/6X/8X PS/N2 series
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 is used to control the
character matrix and lines per row.
Display Features available in each mode
The following is a list of features available in each mode.
Each setting can either be a serial or parallel attribute, and
some have a global effect on the display.
