13 COMBINATION OF TWO OR MORE FONT CELLS
TO FORM A NEW FONT
The user can combine two (or more) font cells to form a
new higher resolution pattern; see Figs 40, 41, 42 and 43.
Combination of two cells in horizontal direction needs no
special care. All 4 background/shadowing modes are
applicable; see Figs 40 and 41.
However the combination of two cells in a vertical direction
needs the following special care:
Space between two rows should be programmed as ‘0’
(bit
<
1-0
>
of Carriage Return Code = 00).
Row 0 in the character ROM is to be used in the
North-west shadowing mode. If this mode is intended for
use by this formed character font, the ROW 0 should
contain the bit pattern of Row 18 of the font above it
(see Figs 42 and 43).
