19.3.6
BACKGROUND COLOUR
The control character new background (1DH) is used to
change the background colour to the current foreground
colour. The selection is immediate (set at) and remains
valid until the end of the row or until otherwise modified.
The TEXT background control characters map to the
CLUT entries as shown in Table 16.
Table 16 Background CLUT mapping
19.3.7
FRINGING
The display of fringing is controlled by the TXT4.SHADOW
bit.
When set all the alphanumeric characters being displayed
are shadowed, graphics characters are not shadowed.
19.3.8
MESHING
The attribute effects the background colour being
displayed. Alternate pixels are displayed as the
background colour or video. The structure is offset by
1 pixel from scan line to scan line, thus achieving a
checker board display of the background colour and video.
TXT: There are two meshing attributes one that only
affects black background colours TXT4.B MESH ENABLE
and a second that only affects backgrounds other than
black TXT4.C MESH ENABLE. A black background is
defined as CLUT entry 8, a non-black background is
defined as CLUT entry 9 to 15.
19.3.9
CURSOR
The cursor operates by reversing the background and
foreground colours in the character position pointed to by
the active cursor position. The cursor is enabled using
TXT7.CURSOR ON. When active, the row the cursor
appears on is defined by TXT9.R<4:0> and the column is
defined by TXT10.C<5:0>. The position of the cursor can
be fixed using TXT9.CURSOR FREEZE.
The valid range for row positioning is 0 to 24. The valid
range for column is 0 to 39.
