DESCRIPTION OF LSI
I/O
Damper motor relay driving signal.
To turn on and off shut-off relay (RY8).
Touch control transformer driving signal.
To turn on and off the shut off relay (RY5). If the oven has not been used for more
than 2 minutes, the relay RY5 will be turned off. The relay RY5 will be turned on
when the oven door is opened and closed.
Tact switch strobe signal.
Signal applied to tact switch section. A pulse signal is input to P70 - P73 terminal
while one of J-6 line tact switches on matrix is touched.
Tact switch strobe signal.
Signal applied to tact switch section. A pulse signal is input to P70 - P73 terminal
while one of J-5 line tact switches on matrix is touched.
Tact switch strobe signal.
Signal applied to tact switch section. A pulse signal is input to P70 - P73 terminal
while one of J-2 line tact switches on matrix is touched.
Tact switch strobe signal.
Signal applied to tact switch section. A pulse signal is input to P70 - P73 terminal
while one of J-1 line tact switches on matrix is touched.
Terminal not used.

Data output terminal to LCD driver IC3.
Data output terminal to LCD driver IC3.
Data output terminal to LCD driver IC3.
IN
Input terminal to change the specification of model.

IN
Connected to GND.
IN
Connected to VC.
IN
Heating constant compensation terminal.
IN
Signal coming from potentiometer.
By inputting DC voltage corresponding to the cooking mode set by the potentiometer,
this input is converted into cooking mode by the A/D converter built into the LSI.
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.
IN
Input signal which communicates the door open/close information to LSI.
Door closed; "H" level signal.
Door opened; "L" level signal.
IN
Terminal not used.
