1.2 HOW TO SELECT MASK OPTIONS
To select mask options, use the option setting command (OC) of the Character Pattern Editor, a tool designed for editing
character pattern data.
Activate the Character Pattern Editor, then display the following setting menu:
OC (COMMAND INPUT)
OPTION DATA (0---LSB FAST
OPTION DATA (0---V:9H
OPTION DATA (0---RGB+3BLK , 1---RGB+V
C1
+V
C2
) :
OPTION DATA (0---OUTPUT 20, 1---OUTPUT 21
OPTION DATA (0---OUTPUT 10, 1---OUTPUT 11
OPTION DATA (0---EXT CLK
OPTION DATA (0---LC
, 1---MSB FAST
, 1---V:3H
) :
) :
......... (1)
......... (2)
......... (3)
......... (4)
......... (5)
......... (6)
......... (7)
) :

) :
, 1---LC
, 1---EXT CLK
Actually, the above menu is displayed one line at a time. Once you have selected an option, the next line is displayed.
Select 0 or 1 for lines (1), (2), (3), (6), and (7), according to the setting to be made. For the dot clock, however, make
the same settings (different values) for lines (6) and (7). For example, when selecting LC oscillation, select “LC” for both
lines (1 for (6) and 0 for (7)). Don’t select external clock input for lines (6) and/or (7).
When selecting the output distribution format, select the values on lines (4) and (5) as follows:
(4)
(5)
Option A
1(OUTPUT 21)
0(OUTPUT 10)
Option B
0(OUTPUT 20)
0(OUTPUT 10)
Option C
1(OUTPUT 21)
1(OUTPUT 11)
The settings are valid only when RGB+V

mode has been selected. Select option A (1, 0) when RGB+3BLK mode
has been selected.
The following table lists the correspondence between the command bits and the lines of the setting menu. Specify 0
or 1 for each bit.

Command OD displays the result of the selection, as a hexadecimal number.
Example: When the mask options are selected as follows:
Mask option

D4
0
Option A (only option A can be
specified in RGB+3BLK mode)
D3
