When either G13 line on key matrix is touched, a corresponding signal will be input into AIN7.

 

 

 

 

 

 

48

AIN6

IN

Input terminal to judge the model.

 

 

 

 

The signal out of P02 will be input into AIN6 through G6 line on key matrix. The LSI will

 

 

 

judge the model by this signal.

 

 

 

 

 

 

 

49

AIN5

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.

 

 

 

 

 

 

 

50

AIN4

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.

 

 

 

 

 

 

 

51

RESET

IN

Auto clear terminal.

 

 

 

 

Signal is input to reset the LSI to the initial state when power is applied. Temporarily set

 

 

 

"L" level the moment power is applied, at this time the LSI is reset. Thereafter set at "H"

 

 

 

level
