Pin No. Signal I/O Description
5 AN7 IN Used for initial balancing of the bridge circuit (absolute humidity sensor). This input is
an analog input terminal from the AH sensor circuit, and connected to the A/D
converter built into the LSI.
6 AN6 IN
AH sensor input.
This input is an analog input terminal from the AH sensor circuit, and connected to the
A/D converter built into the LSI.
7-9 AN5-AN3 IN Heating constant compensation terminal.
10 AN2 IN Input signal which communicates the door open/close information to LSI.
Door closed; "H" level signal(0V).
Door opened; "L" level signal(-5V).
11 AN1 IN Input signal which communicates the damper open/close information to LSI.
Damper opened; "H" level signal(0V:GND).
Damper closed; "L" level signal(-5V).
12 AN0 IN
Temperature measurement input: OVEN THERMISTOR.
By inputting DC voltage corresponding to the temperature detected by the thermistor,
this input is converted into temperature by the A/D converter built into the LSI.
13 P55 OUT
Digit selection signal.
The relationship between digit signal and digit are as follows;
Digit signal Digit
P03........................... 1st.
P02.......................... 2nd.
P01........................... 3rd.
P00........................... 4th.
P37........................... 5th.
P36.......................... 6th.
P35.......................... 7th.
P55.......................... 8th.
Normally, one pulse is output in every ß
period, and input to the grid of the Fluores-
cent Display.
14 P54 OUT Oven lamp and turntable motor driving signal. (Square Waveform : 60Hz)
To turn on and off the shut-off relay(RY1).
The square waveform voltage is delivered to
the relay(RY1) driving circuit.
15 P53 OUT Convection motor driving signal.
To turn on and off shut-off relay(RY5). "L"
level during CONVECTION; "H" level other-
wise.
16 P52 OUT Cooling fan motor driving signal.
To turn on and off shut-off relay(RY6). "L"
level during both microwave and convection
cooking; "H" level otherwise.
17 P51 OUT Magnetron high-voltage circuit driving
signal.
To turn on and off the cook relay(RY2). In
P-HI operation, the signals holds "L" level
during microwave cooking and "H" level
while not cooking. In other cooking modes
(P-90, P-80, P-70, P-60, P-50, P-40, P-30,
P-20, P-10, P-0) the signal turns to "H"
level and "L" level in repetition according
to the power level.
