Power supply
Power supply for internal logic.
Recommended voltage is:
GND = 0V
V
CC
= 2.7 to 5.5V
Power supply for liquid crystal display drive circuit.
Recommended power supply voltage is V
CC
–V
= 8 to
16V. Connect the same power supply to V
and V
.
V
EE1
and V
EE2
are not connected each other in the LSI.
Power supply for liquid crystal display drive.
Apply the voltage specified depending on liquid crystals
within the limit of V
EE
through V
CC
.
V1L (V1R), V2L (V2R): Selection level
V3L (V3R), V4L (V4R): Non-selection level
Power supplies connected with V1L and V1R (V2L &
V2R, V3L & V3R, V4L & V4R) should have the same
voltages.

Enable.
At write (R/W = low): Data of DB0 to DB7 is latched at
the fall of E.
At read (R/W = high): Data appears at DB0 to DB7
while
E is at high level.

MPU
Read/write.
R/W = High:Data appears at DB0 to DB7 and can be
read by the MPU.
When E = high,
&6
,
&6
= low and
CS3 = high.
R/W = Low: DB0 to DB7 can accept at fall of E when
&6

Data/instruction.
D/I = High: Indicates that the data of DB0 to DB7 is
display data.
D/I = Low: Indicates that the data of DB0 to DB7 is
display control data.
