1 AN10 IN Signal coming from touch key.
When either G10 line on key matrix is touched, a corresponding signal out of P10 - P17
will be input into ANI0. When no key is touched, the signal is held at "H" level.
2 AN11 IN Signal similar to AN10.
When either G9 line on key matrix is touched, a corresponding signal will be input into AN11.
3 AVSS IN Connected to VC.
4 P10 OUT Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to AN8 - AN11 terminal while
one of G8 line keys on key matrix is touched.
5 P11 OUT Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to AN8 - AN11 terminal while
one of G7 line keys on key matrix is touched.
6 P12 OUT Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to AN8 - AN11 terminal while
one of G6 line keys on key matrix is touched.
7 P13 OUT Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to AN8 - AN11 terminal while
one of G5 line keys on key matrix is touched.
8 P14 OUT Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to AN8 - AN11 terminal while
one of G4 line keys on key matrix is touched.
9 P15 OUT Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to AN8 - AN11 terminal while
one of G3 line keys on key matrix is touched.
10 P16 OUT Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to AN8 - AN11 terminal while
one of G2 line keys on key matrix is touched.
11 P17 OUT Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to AN8 - AN11 terminal while
one of G1 line keys on key matrix is touched.
12 X1 IN Connected to GND.
13 X2 OUT Terminal not used.
14 VSS IN Power source voltage : -5.0V.
The power source voltage to drive LSI is input to VSS terminal. Connected to VC.
15 OSC2 OUT Internal clock oscillation output.
Output to control oscillation input of OSC1.
16 OSC1 IN Internal clock oscillation frequency control input setting.
The internal clock frequency is set by inserting the ceramic filter oscillation circuit with
respect to OSC2 terminal.
17 TEST IN Connected to VC.
18 RES IN Auto clear terminal.
Signal is input to reset the LSI to the initial state when power is applied. Temporarily set "L"
level the moment power is applied, at this time the LSI is reset. Thereafter set at "H" level.
19 P20 OUT Signal to sound buzzer (2.0 kHz).
A: key touch sound.
B: Completion sound.
20-22 P21-P23 OUT Terminal not used.
