The relation between signals are as follows:
LSI signal (Pin No.)
SEG 0 (1) ................................... S12
SEG 1 (2) ................................... S11
SEG 2 (3) ................................... S10
SEG 3 (4) ..................................... S9
SEG 4 (5) ..................................... S8
SEG 5 (6) ..................................... S7
IN
Signal coming from touch key.
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.
IN
Signal similar to R60.
When either G11 line on key matrix is touched, a corresponding signal will be input into R61.
IN
Signal similar to R60.
When either G10 line on key matrix is touched, a corresponding signal will be input into R62.
IN
Signal similar to R60.
When either G9 line on key matrix is touched, a corresponding signal will be input into R63.
IN
To input signal which communicates the door open/close information to LSI.
Door close "H" level signal (0V). Door open "L" level (-5V)
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.
IN
Power source voltage: -5V
VSS voltage of power source circuit input.
