Terminal not used.
IN Power source voltage : -5.0V.
The power source voltage to the LSI is input to VSS terminal. Connected to VC.
Terminal not used.
IN Used for initial balancing of the bridge circuit (absolute humidity sensor).
IN 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.
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.
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.
Terminal not used.
Signal to sound buzzer (2.0 kHz).
A: key touch sound.
B: Completion sound.
