Abstract
The interrupt regenerator circuit converts the transition signal caused by a passenger's data entry in an aircraft entertainment system into a triggering signal. The triggering signal triggers a delay element consisting of cascadable one-shot devices. The timing intervals for the outputs of these one-shot devices are programmable through the selection of proper values for the resistors and capacitors. The interrupt signal is de-asserted by the host processor when the host processor responds to the interrupt. The delayed interrupt signal is then gated by the interrupt signal itself to regenerate the interrupt signal to the host processor.
