When either G12 line on key matrix is touched, a corresponding signal out of R73, R81-R83
and R90-R91 will be input into R60. When no key is touched, the signal is held at "H" level.
14
R61
IN
Signal similar to R60.
When either G11 line on key matrix is touched, a corresponding signal will be input into R61.
15
R62
IN
Signal similar to R60.
When either G10 line on key matrix is touched, a corresponding signal will be input into R62.
16
R63
IN
Signal similar to R60.
When either G9 line on key matrix is touched, a corresponding signal will be input into R63.
17
AIN0
IN
To input signal which communicates the door open/close information to LSI.
Door close "H" level signal (0V). Door open "L" level (-5V)
18-20
AIN1-AIN3
IN
Terminal to change functions 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 function.
21
