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-P22
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.)

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.
34
INT0
IN
Signal synchronized with commercial power source frequency.
This is the basic timing for time processing of LSI.
35
P07
OUT
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to AIN7, P14, P15, P16 and P17
terminal while one of G1 line keys on key matrix is touched.
36
P06
OUT
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to AIN7, P14, P15, P16 and P17
terminal while one of G2 line keys on key matrix is touched.
