    Preliminary specification
    Enhanced TV microcontrollers with
    On-Screen Display (OSD)
    SAA55xx
    19.3.14 C
    URSOR
    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.
    CC:
     The valid range for row is 0 to 15. The valid range for
    column is 0 to 47. The cursor remains rectangular at all
    times, it’s shape is not affected by italic attribute, therefore
    it is not advised to use the cursor with italic characters.
    TXT:
     The valid range for row positioning is 0 to 24.
    The valid range for column is 0 to 39.
    19.3.15 S
    PECIAL GRAPHICS CHARACTERS
    CC/TXT:
     Several special characters are provided for
    improved OSD effects. These characters provide a choice
    of 4 colours within a character cell. The total number of
    special graphics characters is limited to 16.
    They are stored in the character codes 8XH and 9XH of
    the character table (32 ROM characters), or in the DRCs
    which overlay character codes 8XH and 9XH. Each
    special graphics character uses two consecutive normal
    characters.
    Fringing, underline and overline is not possible for special
    graphics characters. Special graphics characters are
    activated when TXT20.OSD PLANES = 1.
    If the screen colour is transparent (implicit in mixed mode)
    and inside the object the box attribute is set, then the
    object is surrounded by video. If the box attribute is not set
    the background colour inside the object will also be
    displayed as transparent.
