26 P40 OUT 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.
27 P77 OUT 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.
28 P76 OUT 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.
29 P75 OUT 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.
30 P74 OUT Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P44 - P47
terminal while one of G3 line key on matrix is touched.
31 P73 OUT Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P44 - P47
terminal while one of G2 line key on matrix is touched.
32 P72 OUT Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P44 - P47
terminal while one of G1 line key on matrix is touched.
33 P71 OUT Oven lamp and turntable motor driving signal(Square Waveform : 50Hz).
To turn on and off shut-off relay
(RY1). The square waveform voltage
is delivered to the relay (RY1) driving
circuit.
34 P70 IN Connected to VC.
35 RESET IN Auto clear terminal.
Signal is input to reset the LSI to the initial state when power is applied.
Temporarily set to "L" level the moment power is applied, at this time the LSI is
reset. Thereafter set at "H" level.
36 P81 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.
37 P80 OUT Grill (TOP) heating element driving signal.
To turn on and off the grill heating
element relay (RY3). "L" level
during grill cooking, convection
cooking or dual cooking, "H" level
otherwise. The heater relay turns
on and off within a 48 second time
base in accordance with the
special program in LSI.
