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 : 60Hz).
To turn on and off shut-off relay (RY6). The
square waveform voltage is delivered to
the relay (RY6) 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 P-HI operation, the sig-
nals hold "L" level during microwave
cooking and "H" level while not cook-
ing. In other cooking modes (P-90,
P-80, P-70, P-60, P-50, P-40, P-30,
P-20, P-10, P-0) the signal turns to
"H" level and "L" level in repetition
according to the power level.
37
P80
OUT
Grill heaters (TOP HEATER) driving signal.
To turn on and off the grill heaters relay
(RY3). "L" level during grill (TOP GRILL,
TOP AND BOTTOM) cooking, Con-
vection cooking or Roast 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.
38
XIN
IN
Internal clock oscillation frequency input setting.
The internal clock frequency is set by inserting the ceramic filter oscillation circuit with
respect to XIN terminal.
