OUT
Terminal not used.
OUT
Used for initial balancing of the bridge circuit (absolute humidity sensor).
IN
Connected to GND.
IN
Power source voltage: -5.0V.
The power source voltage to the LSI is input to VSS terminal. Connected to VC.
IN
Terminal not used.
IN
Power source voltage input terminal.
Standard voltage for LCD. Connected to GND.
IN
Power source voltage: GND (0V).
The power source voltage to drive the LSI is input to VCC terminal.

Terminal not used.
OUT
Terminal not used.
OUT
Data output terminal to LCD driver IC3.
OUT
Terminal not used.
OUT
Terminal not used.
IN
Signal similar to AN10.
When either G13 line on key matrix is touched, a corresponding signal will be input into P41.
IN
Signal similar to AN10.
When either G12 line on key matrix is touched, a corresponding signal will be input into P42.
IN
Signal synchronized with commercial power source frequency.
This is the basic timing for time processing of LSI.
IN
A/D converter power source voltage.
The power source voltage to drive the A/D converter in the LSI. Connected to GND.
IN
Used for initial balancing of the bridge circuit (absolute humidity sensor). This input is an
analog input terminal from the AH sensor circuit, and connected to the A/D converter built
into the LSI.
IN
AH sensor input.
This input is an analog input terminal from the AH sensor circuit, and connected to the A/
D converter built into the LSI.
IN
To input signal which communicates the door open/close information to LSI.
Door close "H" level signal (0V). Door open "L" level signal (-5V).
IN
Signal input terminal from thermistor (TH1).
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.
IN
Input terminal to judge the model.
The signal out of P17 will be input into AN8 through G1 line on key matrix. The LSI will judge
the model by this signal.
IN
Signal similar to AN10.
When either G11 line on key matrix is touched, a corresponding signal will be input into AN9.
