P41
IN
Signal similar to AN10.
When either G13 line on key matrix is touched, a corresponding signal will be input into P41.
88
P42
IN
Signal similar to AN10.
When either G12 line on key matrix is touched, a corresponding signal will be input into P42.
89
IRQ0
IN
Signal synchronized with commercial power source frequency.
This is the basic timing for time processing of LSI.
90
AVCC
IN
A/D converter power source voltage.
The power source voltage to drive the A/D convertor built into LSI. connected to GND.
91
AN0
IN
Used for initial balancing of 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.
92
AN1
IN
AH sensor input.
This input is an anlage input terminal from the AH sensor circuit, and connected to the A/
D converter built into the LSI.
93
AN2
IN
To input signal which communicates the door open/close information to LSI.

96-98
AN5-AN7
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.
99
AN8
IN
Input terminal to judge the model.
The signal will be input into AN8 through one of G1 - G8 lines on key matrix. The LSI will
judge the model by this signal.
