12 RESET IN Auto clear terminal.
Signal is input to reset the LSI to the initial state when power is applied. Temporarily
set "L" level the moment power is applied, at this time the LSI is reset. Thereafter set
at "H" level.
13 INTP0 IN Connected to VC.
14 INTP1 IN Signal synchronized with commercial power source frequency.
This is the basic timing for time processing of LSI.
15 P02 OUT Terminal not used.
16 P03 OUT Magnetron high-voltage circuit driving signal.
To turn on and off the cook relay (RY2).
The signals holds "L" level during
microwave cooking and "H" level while not
cooking. In other cooking modes (variable
cooking) the signal turns to "H" level and
"L" level in repetition according to the power
level.
(ON and OFF times for other power level.)
17 P04 OUT Oven lamp, fan motor and turntable motor driving signal
To turn on and off shut off relay (RY1). The
square waveform voltage is delivered to
the RY1 driving circuit and RY2 control
circuit.
18 P05 OUT Terminal not used.
19 P110 OUT Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to ANI7, P100, P101,
P102 and P103 terminal while one of G8 line keys on key matrix is touched.
Pin No. Signal I/O Description
