1-2 P26-P27 OUT Terminal not used.
3-5 P70-P72 OUT Terminal not used.
6 IC IN Connected to VC.
7 X2 OUT Internal clock oscillation output.
Output to control oscillation input to X2.
8X1INInternal clock oscillation frequency control input setting.
The internal clock frequency is set by inserting the ceramic filter oscillation circuit with
respect to X1.
9 VDD1 IN Power source voltage: GND(0V).
The power source voltage to drive LSI is input to VDD1 terminal.
10 XT1 IN Connected to GND.
11 XT2 OUT Terminal not used.
12 RESET 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.
13 INTP0 IN Connected to VC.
14 INTP1 IN Signal synchronized with commercial power source frequency.
This is the basic timing for time processing of LSI.
15 P02 OUT Terminal not used.
16 P03 OUT Magnetron high-voltage circuit driving signal.
To turn on and off the cook relay (RY2). The
signals holds "L" level during microwave cooking
and "H" level while not cooking. In other cooking
modes (variable cooking) the signal turns to "H"
level and "L" level in repetition according to the
power level.
(ON and OFF times for other power level.)
17 P04 OUT Oven lamp, fan motor and turntable motor driving signal
To turn on and off shut off relay (RY1). The
square waveform voltage is delivered to the RY1
driving circuit and RY2 control circuit.
18 P05 OUT Terminal not used.
19 P110 OUT Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to ANI7, P100, P101, P102
and P103 terminal while one of G8 line keys on key matrix is touched.
20 P111 OUT Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to ANI7, P100, P101, P102
and P103 terminal while one of G7 line keys on key matrix is touched.
21 P112 OUT Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to ANI7, P100, P101, P102
and P103 terminal while one of G6 line keys on key matrix is touched.
22 P113 OUT Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to ANI7, P100, P101, P102
and P103 terminal while one of G5 line keys on key matrix is touched.
