Terminal not used.
18 VSS IN Power source voltage : -5.0V.
The power source voltage to the LSI is input to VSS terminal. Connected to VC.
19-21 P27-P25 OUT Terminal not used.
22-26 P24-P20 IN Used for initial balancing of the bridge circuit (absolute humidity sensor).
27 P47 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).
28 P46 OUT Terminal not used.
29 P45 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.
30 P44 OUT 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.
(ON and OFF times for other power level.)
31 P43 OUT Terminal not used.
32 CNTR0 OUT Signal to sound buzzer (2.0 kHz).
A: key touch sound.
B: Completion sound.
33 P41 OUT Terminal not used.
16.7 msec.
