Description
28-31
ANI0-ANI3
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.
32
ANI4
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.
33
ANI5
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.
34
ANI6
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.
35
ANI7
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.
36
VDD0
IN
Power source voltage : GND(0V).
The power source voltage to drive LSI is input to VDD0 terminal.
37
AVREF
IN
A/D converter power source voltage : GND(0V).
The power source voltage to drive the A/D converter. Connected to GND.
38
P100
IN
Signal similar to ANI7.
When either G12 line on key matrix is touched, a corresponding signal will be input into P100.
39
P101
IN
Signal similar to ANI7.
When either G11 line on key matrix is touched, a corresponding signal will be input into P101.
40
VSS1
IN
Power source voltage : -5.0V.
The power source voltage to the drive LSI is input to VSS1 terminal. Connected to VC.
41
P102
IN
Signal similar to ANI7.
When either G10 line on key matrix is touched, a corresponding signal will be input into P102.
42
P103
IN
Signal similar to ANI7.
When either G9 line on key matrix is touched, a corresponding signal will be input into P103.

OUT
Signal to sound buzzer (2.0 kHz).
A: Key touch sound.
B: Completion sound.
50
P37
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).
