1.3 - Row Attributes
There are 11row attributes,numbered from 0 to 10. They may be written one by oneor sequentially.
The row attributeformatis as follows :
11

HPOS OFFSET
RE
FBE
VPOS OFFSET
VPOS OFFSET : the MSBis thesignbit (0 :positive,1 :negative).Ifthe offsetis positive(from 0 to +17),
then the corresponding number of lines are added on top of the row (i.e. it moves
downwards). These extra lines are colored according to the character background
rules. If the offsetis negative(from -1 to -17), then the correspondingnumber of lines
are subtractedfrom the display of the row.
FBE
: FBE=0 : the charactersare displayed without border
FBE=1 : the charactersare displayed with border
RE
: RE=0 :
the characters of the row are not displayed.
They are replacedby the pagebackgroundcolor.
the characters of the row are displayed.
HPOS OFFSET : The displayoftherowis shifted tothe right bythecorrespondingnumberof pixels(from
0 to15).
RE=1 :
1.4 - The Control Registers
