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

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.
