A programmable event generator for generating digital timing waveforms in response to a triggering signal includes one programmable read-only memory for storing and outputting data words corresponding to the digital timing waveforms and next address words to address another of the data words, a storage register for temporarily storing and outputting any one of the data words and next address words, another mapping programmable read-only memory for storing and outputting starting address words to start the addressing of the one programmable read only memory, a multiplexer to select either a starting address word or a next address word to address the one programmable read-only memory, and a programmable control circuit, responsive to the triggering signal, for clocking the storage register at a programmed clock frequency. |
