Abstract
An electronic timepiece having a control circuit for controlling operation of the timepiece circuit, and an input switching circuit. The input switching circuit includes a plurality of manually operable switches, and a programmed logic array for receiving signals from the manually operating switches and for developing output signals applied to the control circuit for controlling the control circuit. The input switching circuit further includes a memory having an input for receiving output signals from the programmed logic array, and an output for applying memory output signals to the input of the programmed logic array. The memory has a delay for delaying control of the control circuit, in response to actuation of the manually operable switches, for an interval sufficient to allow an operation being performed by the timepiece circuit to be completed without being interrupted by actuation of the manually operable switches.
