1.1 MASK CODE OPTIONS
The
μ
PD6461,
μ
PD6462 provide mask options for selecting the following items:
(1)
Data transfer
Select the command transfer format.
(2)
Vertical display start position
Select the units used for specifying the vertical display start position of the character display area. In three-line units,
the vertical display start position can be set more finely than in nine-line units.
(3)
Pin selection
Select the pins used to output character signals. In RGB+V
C1
+V
C2
mode, character signals are output from the V
R
,
V
G
, V
B
, V
BLK

, and BLK1 pins.
When displaying colored characters in a color viewfinder, select RGB+V
C1
+V
C2
mode. When assigning a separate
character signal for each color, select RGB+3BLK mode.
(4)
Output distribution format
Select the format to be used to distribute character signals to the V
C1
and V
C2
channels when RGB+V
C1
+V
C2
mode
is selected. (When RGB+3BLK mode is selected, select option A as the output distribution format. Options B and C
are invalid.)
When an on-screen IC is used in a camcorder, some information is displayed in the viewfinder and recorded onto
video tape (such as a date and title). Other information, however, need only be displayed in the viewfinder (battery
or focus alarm and tape count). The
μ
PD6461, 6462 can distribute such information to different output channels in
units of rows or half rows. You can select option A, option B, and option C as the output distribution format (only when
RGB+V
C1
+V
C2
mode is selected).
(5)
Dot clock
Select the dot clock to be used to display characters. When an external clock input is selected, refer to
