PD6466
This command sets the information selected by a mask code option in the
μ
PD6461 and 6462.
The default setting is as follows:
OSC
VST
COC
= 0
= 0
= 0
: LC oscillation
: 3-row units
: RGB + V
C1
+ V
C2
(OP1, OP0) = (0, 1) : Option B
RS
= 0
BR
= 0
: Black character
: Character blinks
Dot clock control
The dot clock for character display is set.
The dot clock is selected from LC oscillation and external clock input.
Vertical display start position control
The character display start position and setting accuracy are set.
The setting accuracy is selected from 3 rows and 9 rows.
Pin selection control
The output pins of the character and blanking signals are set.
The output pins are selected from the following two types:
RGB + V
C1
+ V
C2
RGB + RGB compatible BLK: Signal output pins = V
R

Output selection control
The output formats of V
C1
and V
C2
are set.
The output formats are selected from options A, B, and C (refer to
1.3 Display with RGB + V
C1
+ V
C2
Pins
).
The output formats are set only when RGB + V
C1
+ V
C2
is selected by means of pin selection control. Select
option B when RGB + RGB compatible BLK is selected.
Character color reverse control
The character when color displayed is turned ON is specified.
Select the character from black character (with frame specification invalid) or white character (with frame
specification valid) (refer to
3.5 Character Color Reverse ON/OFF Command
).
