Input signal which communicates the door open/close information to LSI.
Door closed; "H" level signal.
Door opened; "L" level signal.
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.
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 LSI.
This input is an analog input terminal from the AH sensor circuit, and connected
to the A/D converter built into the LSI.
Timing signal output terminal for temperature measurement(OVEN
THERMISTOR).
"H" level (GND) : Thermistor OPEN timing.
"L" level (-5V) : Temperature measuring timing. (Convection cooking)
Signal to sound buzzer.
A: key touch sound.
B: Completion sound.
C: When the temperature of the oven
c a v i t y r e a c h e s t h e p r e s e t
temperature in the preheating mode,
or when the preheating hold time (30
minutes) is elapsed.
Timing signal output terminal for temperature measurement(OVEN
THERMISTOR).
"H" level (GND) : Thermistor OPEN timing.
"L" level (-5V) : Temperature measuring timing. (Convection cooking)
Used for initial balancing of the bridge circuit (absolute humidity sensor).
Signal coming from touch key.
When any one of G12 line keys on key matrix is touched, a corresponding signal
from P40, P41, P72, P73, P74, P75, P76 and P77 will be input into P47. When no
key is touched, the signal is held at "L" level.
Signal similar to P47.
When any one of G11 line keys on key matrix is touched, a corresponding signal
will be input into P46.
Signal similar to P47.
When any one of G10 line keys on key matrix is touched, a corresponding signal
will be input into P45.
Signal similar to P47.
When any one of G9 line keys on key matrix is touched, a corresponding signal will
be input into P44.
Terminal not used.
Signal to synchronized LSI with commercial power source
frequency(50Hz).
This is basic timing for time processing of LSI.
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P44 - P47 terminal
while one of G8 line key on matrix is touched.
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P44 - P47 terminal
while one of G7 line key on matrix is touched.
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P44 - P47 terminal
while one of G6 line key on matrix is touched.
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P44 - P47 terminal
while one of G5 line key on matrix is touched.
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P44 - P47
terminal while one of G4 line key on matrix is touched.
