Integrated circuit for a time-piece

Claim 1

An integrated circuit for a timepiece having means responsive to control signals for displaying time data, a power source, and manually actuated time setting elements for producing time setting signals, the integrated circuit comprising: a first group of terminals including first terminals connecting the displaying means with the integrated circuit, and second terminals connecting the power source and the time setting elements with the integrated circuit; means for producing a time base signal; means responsive to said time base signal and to the time setting signals for producing the controls signals, the control signals being applied to said first terminals; means connected to selected ones of said first terminals and to selected ones of said second terminals for storing a data signal in response to a first predetermined combination of voltages applied simultaneously to said selected first terminals and to said selected second terminals, said data signal being determined by the control signals present at said selected first terminals; and means connected to said storing means for performing an auxiliary function of the timepiece in response to said data signal.
