PURPOSE: To provide a pulse control circuit setting uniquely the resolution of a pulse for a register or the like connected to a counter without revising the resolution of the counter especially.

CONSTITUTION: The pulse control circuit is provided with a counter C1 counting the number of inputted pulses, registers CR1, CR2, CR3 latching data to be compared with the counted value of the counter C1, and comparators MC1, MC2, MC3 with a mask function connected to the registers CR1, CR2, CR3 and the counter C1, extracting bit data of a prescribed part of the counter C1, comparing the data with the data of the registers CR1, CR2, CR3 and outputting a signal in response to the result of comparison. The resolution is varied by controlling the location of the bit data to be extracted.
