DESCRIPTION OF LSI
I/O
IN
Terminal not used.
OUT
Timing signal output terminal for temperature measurement(OVEN
THERMISTOR).
"H" level (GND) : Thermistor OPEN timing.
"L" level (-5V) : Temperature measuring timing. (Convection cooking)
OUT
Timing signal output terminal for temperature measurement(OVEN
THERMISTOR).
"H" level (GND) : Thermistor OPEN timing.
"L" level (-5V) : Temperature measuring timing. (Convection cooking)
OUT
Terminal not used.
IN
Signal coming from touch tact switch.
When any one of J-3 line tact switches on tact switch matrix is touched, a
corresponding signal from P14, P15, P16 and P17 will be input into P73. When no
tact switch is touched, the signal is held at "L" level.
IN
Signal similar to P73.
When any one of J-4 line tact switches on tact switch matrix is touched, a
corresponding signal will be input into P72.
IN
Signal similar to P73.
When any one of J-7 line tact switches on tact switch matrix is touched, a
corresponding signal will be input into P71.
IN
Signal similar to P73.
When any one of J-8 line tact switches on tact switch matrix is touched, a
corresponding signal will be input into P70.
OUT
Terminal not used.
OUT
Signal to sound buzzer.
A: Tact switch touch sound.
B: Completion sound.
C: When the temperature of the oven
cavity
reaches
temperature in the preheating mode,
or when the preheating hold time (30
minutes) is elapsed.
OUT
Terminal not used.
IN
Signal coming from encoder.
When the encoder is turned, the contacts of encoder make pulse signals. And
pulse signal is input into P47.
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:VC).
OUT
Terminal not used.
OUT
Magnetron high-voltage circuit driving signal.
To turn on and off the cook relay
(RY2). In 100% operation, the
signals hold "L" level during
microwave cooking and "H" level
while not cooking. In other
cooking modes (70%, 50%, 30%,
10%) the signal turns to "H" level
and "L" level in repetition
according to the power level.
IN
Signal coming from encoder.
Signal similar to P47. Pulse signals are input into INT1.
