Functions
RESET*
1
I
MPU or external
R-C circuit
Reset pin. Initializes the LSI when low. Must be reset
after power-on.
OPOFF
1
I
V
CC
or GND
Turns the internal operational amplifier off when
OPOFF = V
, and turns it on when OPOFF = GND.
If the amplifier is turned off (OPOFF = V
), V1 to V5
must be supplied to the V1OUT to V5OUT pins.
VccDUM
1
O
Input pins
Outputs the internal V
level; shorting this pin sets
the adjacent input pin to the V
CC
level.
Outputs the internal GND level; shorting this pin sets
the adjacent input pin to the GND level.

TEST
1
I
GND
Test pin. Must be fixed at GND level.
VTEST1
1
I
Vcc or GND
Adjust the driving ability of the internal LCD
operational amplifier. Normal drive mode in the GND
side, and high-power drive mode in the Vcc side.
Use the high-power drive mode when the display
quality is insufficient although current consumption
increases.
VTEST2
1
Test pin. Must be open.
VTEST3
1
I
Vcc or GND
Adjust the driving ability of the internal LCD
operational amplifier.
Normal drive mode or high-power drive mode in the
GND side, and low-power drive mode in the Vcc side.
