LCD driver power supply
VL1
VL2
VL3
Power supply pins for LCD bias (internally generated). Capacitors Ca, Cb,
and Cc (see measuring circuit 1) are connected between VSS and VL1, VL2,
and VL3, respectively.
C1
C2
Power supply pins for LCD bias (internally generated). Capacitors C12 is
connected between C1 and C2.
For testing
TEST
I/O
Input/output pin for testing. A pull-down resistor is internally connected.
Power supply
VSS
Negative power supply pin.
VDD
Positive power supply pin for I/O, internal regulator, battery low detector,
and power-on reset.
VDDL
Positive power supply pin (internally generated) for internal logic.
Capacitors CL0 and CL1 (see measuring circuit 1) are connected between
this pin and VSS.
VDDX
