Terminal not used.
22-26
P24-P20
IN
Terminal not used.
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 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.
