18.6.1 Character Display Area
The character display area consists of 3 bytes for each character position of the
character display area. These three bytes are used to store the character
display word as it is described in chapter 18.3.
The array is sorted in a incremental serial order coming from the top left
character throughout the bottom right character of the character display area.
For further information see chapter 18.2.
The length of this display memory area depends on the parameter settings of
DISALH0..DISALH4.
18.6.2 CLUT Area
The CLUT area consist of 48 x 2 Byte CLUT contents. The CLUT contents are
stored in a serial incremental order.
For further information see chapter 18.4.7.
The length of the CLUT is fixed to 96 bytes.
18.6.3 Global Display Word/Cursor
The area of the global display word is fixed to 10 byte. All the global display
relevant informations are stored inside global display word (GDW; see also
18.4). See also 18.2. The cursor matrix for cursor display is stored after the
global display word.
The length of the memory area of global display word is fixed to 10 byte. The
length of the memory area of cursor matrix depends on the settings of
CHADRC2..CHADRC0.
