When the 2 key of the transparent electrode is touched, a corresponding signal out of
OUT3 of IC-2 will be input into P95 of IC-1.
3
P94
IN
Signal coming from Transparent electrode (touch key on the LCD).
When the 3 key of the transparent electrode is touched, a corresponding signal out of
OUT4 of IC-2 will be input into P94 of IC-1.

5
P92
IN
Signal coming from Transparent electrode (touch key on the LCD).
When the 4 key of the transparent electrode is touched, a corresponding signal out of
OUT1 of IC-3 will be input into P92.
6
P91
IN
Signal coming from Transparent electrode (touch key on the LCD).
When the 5 key of the transparent electrode is touched, a corresponding signal out of
OUT3 of IC-3 will be input into P91.
7

8
BYTE
IN
Connected to VCC1.
9
CNVSS
IN
Power source voltage: 0V (GND).
The power source vpltage to drive the LSI (IC-1) is input. Connected to GND.
10
P87
OUT
Memory (EEPROM) clock out.
11
P86
IN/OUT Memory (EEPROM) data input/output.
12
RESET
IN
Auto clear terminal.
Signal is input to reset the LSI to the initial state when power is applied. Temporarily set
to “L” level the moment power is applied, at this time the LSI is reset. Thereafter set at “H”
level.
13
XOUT
OUT
Internal clock oscillation frequency control output.
Output to control oscillation input of Xin.
14
VSS
IN
Power source voltage: 0V (GND).
The power source vpltage to drive the LSI (IC-1) is input. Connected to GND.
15
XIN
IN
Internal clock oscillation frequency setting input.
The internal clock frequency is set by inserting the ceramic filter oscillation circuit with
respect to Xout terminal.
16
VCC1
IN
