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.
Terminal not used.
Magnetron high-voltage circuit driving signal.
To turn on and off the cook relay (RY2). The
signals holds "L" level during microwave cook-
ing 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.
A/D converter power source voltage.
The power source voltage to drive the A/D converter in the LSI. Connected to GND.
Terminal to change cooking input according to the Model.
By using the A/D converter contained in the LSI, DC voltage in accordance with the Model
in operation is applied to set up its cooking constant.
This is the terminal to detect the voltage of the signal coming from the touch key.
Signal similar to AIN1.
A/D converter power source voltage.
The power source voltage to drive the A/D converter in the LSI.
To input signal which communicates the door open/close information to LSI.
Door close "H" level signal (0V). Door open "L" level signal (-5V).
Terminal not used.
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P50, P51, P52 and P53 terminal
while one of G1 line keys on key matrix is touched.
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P50, P51, P52 and P53 terminal
while one of G2 line keys on key matrix is touched.
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P50, P51, P52 and P53 terminal
while one of G3 line keys on key matrix is touched.
Signal synchronized with commercial power source frequency.
This is the basic timing for time processing of LSI.
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P50, P51, P52 and P53 terminal
while one of G4 line keys on key matrix is touched.
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P50, P51, P52 and P53 terminal
while one of G5 line keys on key matrix is touched.
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P50, P51, P52 and P53 terminal
while one of G6 line keys on key matrix is touched.
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P50, P51, P52 and P53 terminal
while one of G7 line keys on key matrix is touched.
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P50, P51, P52 and P53 terminal
while one of G8 line keys on key matrix is touched.
