Abstract
A pulse signal generation circuit comprises a frequency setting register which is at least (n+1) bits long for setting a value of 2.sup.n or smaller as a frequency value of a pulse signal to be generated, and a cumulative addition circuit having an adder and a flip-flop which is at least (n+1) bits long. The cumulative addition circuit repeats at a rate of 2.sup.n+1 times per second, operations of making the adder add a value set in the frequency setting register to a value held in the flip-flop and then making the flip-flop hold the addition result, and outputs a signal having a value of (n+1)th bit in the flip-flop as the pulse signal.
