Abstract
A pulse generating apparatus equipped with a first comparator (20) for comparing the count value of a timer register (9) with the reference value of a comparing register (10) in terms of each bit and a coincidence detection circuit (21) responsive to the output values of the first comparator (20) to output a coincidence signal when all the bits of the output values thereof are the same. Between the first comparator (20) and the coincidence detection circuit (21) there are provided a plural-bit mask register (17) whose comparison value is set by a CPU (2) and a second comparator (22) for comparing the comparison value of the mask register (17) with the output value of the first comparator (20) in terms of each bit. With this arrangement, the generation timing of the output pulse can variously be changed by setting one time the mask register (17).
