TV microcontrollers with Closed Captioning (CC)
and On-Screen Display (OSD)
SAA55xx
18.10 Redefinable characters
A number of Dynamically Redefinable Characters (DRCs)
are available. These are mapped onto the normal
character codes, and replace the predefined ROM value.
There are 32 DRCs, the first 16 occupy the character
codes 80H to 8FH, the second 16 occupy the locations
90H to 9FH. This allows for 32 DRCs or 16 Special DRCs.
The remapping of the standard OSD to the DRCs is
activated when the TXT20.DRCS ENABLE bit is set.
The selection of Normal or Special OSD symbols is
defined by the TXT20.OSD PLANES.
Each character is stored in a matrix of 12

planes), this allows for all possible character
matrices to be defined within a single location.
