DESCRIPTION OF LSI
Auto clear terminal.
Signal is input to reset the LSI to the initial state when power is supplied.
Connected to GND.
Power source voltage: -5V.
VSS voltage of power source circuit input.
Internal clock oscillation frequency setting input.
The internal clock frequency is set by inserting the resistor oscillation circuit with respect
to OCS4 terminal.
Internal clock oscillation frequency control output.
Output to control oscillation input of OCS3.
Power source for oscillation circuit.
Power source voltage input terminal.
Connected to GND.
A/D converter power source voltage.
The power source voltage to drive the A/D converter in the LSI. Connected to GND.
A/D converter power source voltage.
The power source voltage to drive the A/D converter in the LSI. Connected to GND.
Power source voltage: -5V.
AVSS voltage of power source circuit input. Connected to VSS.
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.
To input signal which communicates the door open/close information to LSI.
Door close "H" level signal (0V). Door open "L" level (-5V).
Signal to sound buzzer (2.0 kHz).
A: key touch sound.
B: Completion sound.
Key strobe signal.
Signal applied to touch-key section. A pulse signal is input to P23, K00, K01 and K02
terminal while one of G1 line keys on key matrix is touched.
