Display modes
The display section has two distinct modes with different
features available in each:
TXT:
This is the WST mode with additional serial and
global attributes. A TXT window is configured as a fixed
25 rows with 40 characters per row.
CC:
This isthe US ClosedCaptionmode. ACC window
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 a
character matrix (H

16, which have 9, 10, 13 and 16 TV lines per display
row, respectively.
Table 27 gives the possible number of display rows for
each combination, as allowed by the hardware.

SFR TXT21 and memory mapped registers are used to
control the mode selection. The features will now be
described and their function in each of the modes given.
If the feature is different in either mode then this is stated.
