73 HWR OUT Write strobe signal is output to WR terminal of IC5.
74 LWR OUT Terminal not used.
75-76 MD0-MD1 IN Connected to VCC.
77 MD2 IN Connected to GND.
78 Avcc IN A/D converter power source voltage : +5V.
The power source voltage to drive the A/D converter. Connected to VCC.
79 Vref IN A/D converter power source voltage : +5V.
The power source voltage to drive the A/D converter. Connected to VCC.
80 AN0 IN Terminal to judge whether the model has the sensor cooking function or not.
By using the A/D converter contained in the LSI, DC voltage in accordance with the
Model in operation is applied to judge whether the model has the sensor cooking
function or not.
81 AN1 IN Input terminal to judge the model.
The signal out of P95 will be input into AN1 through G15 line on key matrix. The LSI
will judge the model by this signal.
82 AN2 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.
83 AN3 IN Connected to VCC.
84 AN4 IN To input signal which communicates the door open/close information to LSI.
Door close "H" level signal (+5V). Door open "L" level signal (GND).
85 AN5 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.
86 AN6 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.
87 DA1 OUT The signal for the power source to drive the LCD is output to IC3.
88 Avss IN A/D converter power source voltage : GND(0V).
The power source voltage to drive the A/D converter. Connected to GND.
89 IRQ0 IN Signal synchronized with commercial power source frequency.
This is the basic timing for time processing of LSI.
