46 P14 IN Signal similar to P17.
When either G12 line on key matrix is touched, a corresponding signal will be input into P14.
47 AIN7 IN Signal similar to P17.
When either G13 line on key matrix is touched, a corresponding signal will be input into AIN7.
48 AIN6 IN Input terminal to judge the model.
The signal out of P07 will be input into AIN6 through G1 line on key matrix. The LSI will
judge the model by this signal.
49-50 AIN5-AIN4 IN Connected to VC.
51 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
52 NC Terminal not used.
53 XCOUT OUT Terminal not used.
54 XCIN IN Connected to VC.
55 NC Terminal not used.
56 VCC IN Power source voltage: GND(0V).
The power source voltage to drive LSI is input to VCC terminal.
57 OSCSEL IN Connected to VC(-5V).
58 XOUT OUT Internal clock oscillation output.
Output to control oscillation input of XIN.
59 VSS IN Power source voltage: -5.0V.
The power source voltage to the LSI is input to VSS terminal. Connected to VC.
60 NC Terminal not used.
61 XIN IN Internal clock oscillation frequency control input setting.
The internal clock frequency is set by inserting the ceramic filter oscillation circuit with
respect to XOUT terminal.
62 NC Terminal not used.
63-66 AIN3-AIN0 IN Terminal to change cooking input according to the Model.
By using the A/D converter contained in the LSI, DC voltage in accordance with the Model
in operation is applied to set up its cooking constant.
