(9) Scanning Line Double Count Mode
1 dot in a displayed character is normally shown with 1 scanning line.
In the scanning double count mode, 1 dot can be shown with 2 scan-
ning lines. As a result, the displayed dot is extended 2 times the
normal size in the vertical direction only (that is to say, the height of a
character is extended twofold.)
In addition, because the scanning line count is doubled, the display
start position of a character becomes also twofold position in the
vertical direction.
In other words, the contents of the vertical position register is as fol-
lows:
In ordinary mode
256 steps as values “00
16
” to “FF
16
”
(4 scanning lines per step)
In scanning line double count mode
128 steps as values “00
16
” to “7F
16
”
(8 scanning lines per step)
If the contents of the vertical position register for a block are set in
the range of “80
16
” to “FF
16
” in the scanning line double count mode,
that block cannot be displayed (not output to the CRT screen). The
scanning line double count mode is specified by setting bit 6 of the
CRT control register 1 (address 00EA
16
) to “1.”
Since this function works in units of a screen, even if the mode is
changed during display of 1 screen, the mode before the change
remains until the display of the next screen.
