Terminal not used.
IN Power source voltage: GND(0V).
The power source voltage to drive LSI is input to VCC terminal.
IN Connected to VC(-5V).
Internal clock oscillation output.
Output to control oscillation input of XIN.
IN Power source voltage: -5.0V.
The power source voltage to the LSI is input to VSS terminal. Connected to VC.
Terminal not used.
IN Internal clock oscillation frequency control input setting.
The internal clock frequency is set by inserting the ceramic filter oscillation circuit with
respect to XOUT terminal.
_
Terminal not used.
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.
