Preliminary specification
Enhanced TV microcontrollers with
On-Screen Display (OSD)
SAA55xx
19.3.12 F
RINGING
A fringe (shadow) can be defined around characters.
The fringe direction is individually selectable in any of the
North, South, East and West direction using the MMR
Fringing Control. The colour of the fringe can also be
defined as one of the entries in the CLUT, again using
MMR Fringing Control.
CC:
The fringe attribute (see Table 22, Serial Mode 0,
bit 9) is valid from the time set until the end of the row or
otherwise modified.
TXT:
The display of fringing in TXT mode is controlled by
the TXT4.SHADOW ENABLE bit.
When set all the alphanumeric characters being displayed
are shadowed, graphics characters are not shadowed.
19.3.13 M
ESHING
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.
CC:
The setting of the MSH bit in MMR Display Control
has the effect of meshing any background colour.
TXT:
There are two meshing attributes one that only
affectsblackbackgroundcoloursTXT4.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.
