Signal similar to P17.
When either G12 line on key matrix is touched, a corresponding signal will be input into P14.
Signal similar to P17.
When either G13 line on key matrix is touched, a corresponding signal will be input into AIN7.
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.
Connected to VC.
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

Connected to VC.
Terminal not used.
Power source voltage: GND(0V).
The power source voltage to drive LSI is input to VCC terminal.
Connected to VC(-5V).
Internal clock oscillation output.
Output to control oscillation input of XIN.
Power source voltage: -5.0V.
The power source voltage to the LSI is input to VSS terminal. Connected to VC.
Terminal not used.
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.
Terminal not used.
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.
