1. INITIAL STATUS SETTING
1.1 Initial Status Setting
The
μ
PD6466 selects the following parameters that are selected by mask code options with the
μ
PD6461 and 6462,
by using an initial status setting command.
Parameter
Selected by:
(1)
Dot clock
LC oscillation
External clock input
(2)
Vertical display start position
3-row unit setting
9-row unit setting
(3)
Pin selection
RGB + V
C1
+ V
C2
RGB + RGB compatible BLK
(RGB + 3BLK)
(4)
Output selection
Option A
Option B
Option C
(5)
Character color reversal
specification selection
Black character
White character
(6)
Function selection
Character blinking
Character left/right reversal
(1) Dot clock
To select a dot clock for character display. If an external clock input is selected, refer to
External Clock Input
in
6. ELECTRICAL CHARACTERISTICS
.
(2) Vertical display start position
To select the setting accuracy of the vertical display start position of the character display area. In 3-row units,
the vertical display start position can be set more finely than in 9-row units.
(3) Pin selection
To select the setting of the output pins.
When RGB + V

When RGB + V
C1
+ V
C2
is selected with a video camera with a color view finder, colored characters can be
displayed in the view finder. When RGB + 3BLK is selected, character signals can be separated color
specification.
(4) Output selection
To set the output format of the character signal where the setting of the output pin is RGB + V
C1
+ V
C2
(setting
the output format of the character signal is invalid where the setting of the output pin is RGB + 3BLK).
When an on-screen character display IC is used in a video camera, some items of information (such as date
and title) are displayed on the video tape, and the others (such as battery alarm, focus, and counter indication)
are only displayed in the view finder. The
μ
PD6466 can select these items of information in row or half-row
units by using the output pin. Select the output format from three types: option A, option B, and option C (when
3BLK is selected, however, be sure to select option B).
(5) Character color reversal specification selection
To select the specifications when the character color is reversed (valid only for RGB output).
Black character: Outputs an area with dots in black and prohibits framing.
White character: Outputs an area with dots in white and prohibits framing.
