1
CLK
Clock input
This pin inputs a clock for reading data. Data input to the DATA pin
is read at the rising edge of this clock.
2
CS
Chip select input
Serial transfer can be accepted if this pin is made low.
3 (4)
DATA
Serial data input
This pin inputs control data. Data is read in synchronization with the
clock input to the CLK pin.
4 (5)
PCL
Power-ON clear
This pin, when high, initializes the internal circuitry of the IC on power
application.
5 (6)
V
DD
Power supply
This pin supplies power.
6 (7)
CMDCT
Command specification
select
This pin selects whether a command is input with the LSB first or MSB
first.
When this pin is low, the command is input with the LSB first; when
it is high, the command is input with the MSB first. To input the
command with the LSB first, this pin may be opened.

OSC
OUT
OSC
IN
LC oscillation I/O
(OSC
IN
: external clock
input)
These are an input and an output pin for an oscillation circuit that
generates a dot clock.
A coil and capacitor for oscillation are connected to these pins. (If
the input of an external clock is selected by the initial status setting
command, an external clock (clock synchronized with Hsync) is input.
OSC
OUT
is opened at this time.)
9 (10)
TEST
Test pin
This pin is used to test the IC. Normally, connect this pin to GND.
When the TEST pin is connected to GND, the test mode is not set.
10 (11)
GND
Ground pin
Connect this pin to GND of the system.
11 (14)
BLK1
Blanking signal output 1
This pin outputs a blanking signal to cut the video signal.
It supports output of V
C1
, and is high-active.
(If RGB compatible blanking is selected by a command, this pin
outputs the logical sum of R
BLK
, G
BLK
, and B
BLK
.)
12 (15)
V
C1
Character signal output 1
This pin outputs a character signal, and is high-active.
(If RGB compatible blanking is selected by a command, this pin
outputs the logical sum of V
R
, V
G
, and V
B
.)
13 (16)
BLK2
(R
BLK
)
Blanking signal output 2
(blanking R)
This pin outputs a blanking signal to cut the video signal. It supports
output of V
C2
, and is high-active.
(This pin outputs a blanking signal supporting output of V
R
and is
high-active.)
14 (17)
V

Character signal output 2
(blanking G)
This pin outputs a character signal, and is high-active.
(This pin outputs a blanking signal supporting output of V
G
and is
high-active.)
15 (18)
V

)
Blanking signal output
(blanking B)
This pin outputs a blanking signal to cut the video signal. It supports
output of V
R
, V
G
, and V
B
, and is high-active (this pin outputs a blanking
signal supporting output of V
B
and is high-active).

Vsync
Vertical sync signal input
This pin inputs a vertical sync signal. Input a negative sync signal.
20 (24)
Hsync
Horizontal sync signal input
This pin inputs a horizontal sync signal. Input a negative sync signal.
