I/O
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
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
Input terminal to judge the model.
The signal out of P112 will be input into ANI6 through G6 line on key matrix. The LSI will
judge the model by this signal.
IN
Signal coming from touch key.
When either G13 line on key matrix is touched, a corresponding signal out of P110 - P117
will be input into ANI7. When no key is touched, the signal is held at "H" level.
IN
Power source voltage : GND(0V).
The power source voltage to drive LSI is input to VDD0 terminal.
IN
A/D converter power source voltage : GND(0V).
The power source voltage to drive the A/D converter. Connected to GND.
IN
Signal similar to ANI7.
When either G12 line on key matrix is touched, a corresponding signal will be input into P100.
IN
Signal similar to ANI7.
When either G11 line on key matrix is touched, a corresponding signal will be input into P101.
IN
Power source voltage : -5.0V.
The power source voltage to the drive LSI is input to VSS1 terminal. Connected to VC.
IN
Signal similar to ANI7.
When either G10 line on key matrix is touched, a corresponding signal will be input into P102.
IN
Signal similar to ANI7.
When either G9 line on key matrix is touched, a corresponding signal will be input into P103.
Terminal not used.
Used for initial balancing of the bridge circuit (absolute humidity sensor).
Signal to sound buzzer (2.0 kHz).
A: Key touch sound.
B: Completion sound.
