Input pin for the data read clock.The data input to the DATA
pin is read at rising edges of the clock.
Serial transfer is accepted when this pin is low.
Input pin for control cata. Data is read in synchronization
with the clock input to the CLK pin.
Pin used for the power-on clear function.After power-on.set
this pin from low to high to initialize the IC.
Power supply pin.
N-ch open-drain output pin used to check the oscillation
frequency
Input and output pins for the oscillator for generating a dot
clock. Connect the oscillation coil and capacitors to these pins
(When an external clock input is selected by specifying a mask
option, input an external clock(synchronized with Hsync) to the
OSC
IN
pin, Leave OSC
OUT
pin open.)
Pin used for testing the IC.Usually, connect this pin to ground.
The IC cannot enter test mode while this pin is connected to
ground.
Connect this pin to the system ground.
Pin used to output the blanking signal for the video signal
output from the V
C1
pin. The blanking signal is high active.
(When RGB separate blanking has been selected by specifying a
mask option, This pin outputs the logical OR of R
BLK
, G
BLK
,and
B
BLK
.)
Pin used to output the blanking signal for the video signal
output from the VC1 pin. The blanking signal is high active.
(When RGB separate blanking has been selected by specifying a
mask option,this pin outputs the logical OR of V
R
, V
G
and V
B.

Pin used to output the blanking signal for the video signal
output from the V
C2
pin. The blanking signal is high active.
(This pin outputs the blanking signal for the video signal
output from the V
R
pin, The blanking signal is high active.)
Pin used to output a high-active character signal.
(This pin outputs the blanking signal for the video signal
output from the V
G
pin. The blanking signal is high active.)
Pin used to output the blanking signal for the video signals
output from the V
R
,V
G
,and V
B
pins. The blanking signal is high
active.
(This pin outputs the blanking signal for the video signal
output from the V
B
pin, The blanking signal is high active.)
Pins used to output high-active character signals.
Input a low-active vertical synchronizing signal to this pin.
Input a low-active horizontal synchronizing signal to this pin
Symbols and functions indicated in parentheses for pins 13 to 15 apply when RGB separate blanking is selected
with a mask option.
