PURPOSE: A programmable clock pulse generator is provided to program clock pulses to be generated, periodically generate programmed clock pulses, and select the generated clock pulses at a predetermined position. CONSTITUTION: A programmable clock pulse generator comprises a reference clock generating unit(100), bit setting units(180 to 230), and parallel input/serial output shift registers(120 to 170). The reference clock generating unit generates a reference clock having a predetermined cycle and duty. The bit setting units set m-number of bit values, and output the set values. The parallel input/serial output shift registers receive, in parallel, m-number of bit values from the bit setting units, and output, in serial, the parallel bit values in synchronization with the reference clock output from the reference clock generating unit.
