CHARACTER TABLE
The character table is shown in Table 24:-
Re-definable Characters
A number of Dynamically Re-definable Characters (DRC) are available. These are mapped onto the normal character
codes, and replace the pre-defined OTP character Rom value.
There are 32 DRCs which occupy character codes 80H to 9FH. Alternatively, These locations can be utilized as 16
special graphics characters. The remapping of the standard OSD to the DRCs is activated when the TXT21.DRCS
ENABLE bit is set. The selection of Normal or Special OSD symbols is defined by the TXT21.OSD PLANES.
Each character is stored in a matrix of 16x16x1 (V x H x planes), this allows for all possible character matrices to be
defined within a single location.
