I/O
OUT
Terminal not used.
OUT
Damper motor relay driving signal.
To turn on and off shut-off relay (RY8).
OUT
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.
OUT
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P70 - P73 terminal
while one of G8 line key on matrix is touched.
OUT
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P70 - P73 terminal
while one of G7 line key on matrix is touched.
OUT
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P70 - P73 terminal
while one of G6 line key on matrix is touched.
OUT
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P70 - P73 terminal
while one of G5 line key on matrix is touched.
OUT
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P70 - P73 terminal
while one of G4 line key on matrix is touched.
OUT
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P70 - P73 terminal
while one of G3 line key on matrix is touched.
OUT
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P70 - P73 terminal
while one of G2 line key on matrix is touched.
OUT
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P70 - P73 terminal
while one of G1 line key on matrix is touched.
OUT
Terminal not used.
OUT
Data output terminal to LCD driver IC3.
OUT
Data output terminal to LCD driver IC3.
OUT
Data output terminal to LCD driver IC3.
IN
Input terminal to change the specification of model.
IN
Connected to GND.
IN
Connected to GND.
IN
Connected to VC.
IN
Heating constant compensation terminal.
OUT
Terminal not used.
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. (For only R-953(SL)M/(W)M)
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. (For only R-963(SL)M/(W)M)
R-953/963M - 22
