Function and Operation
1-72
SEG71-0
O
Output for driving segment of LC
73
A0
I
Normally the lowest bit in the address bus of MPU is connected to distinguish
between data and command.
74,75
OSC1,2
Terminal to connect resistor for internal oscillation
76
E(

wr
)
I
Input terminal of read/write control signal
Terminal to connect write signal of 80-system MPU
78
VSS
0V connect to system GND
79-86
DB0-7
8-bit duplex data bus to be connected to a data bus of 8-bit or 16-bit standard MPU
87
VDD
Connect to +5V power supply VDD
88
res
Can be set to initial setting by setting RES to “L” when using 68-system MPU,
or by setting RES to “H” when using 80-system MPU.
