PROBLEM TO BE SOLVED: To receive serial data stably.SOLUTION: A multiplication circuit 30 multiplies a bit clock BCK by N (N is a natural number) to generate a system clock PLLCK. A first buffer BUF1 and a second buffer BUF2 hold common data stored in a shift register 14 for different periods. A first counter 12 resets a count value to an initial value synchronously with loading of data into the first buffer BUF1. A second counter 56 resets a count value CNT2 thereof to an initial value repeatedly each time the count value reaches a set value. A strobe signal generation unit 58 asserts a first strobe signal STRB1 each time the count value CNT2 of the second counter 56 reaches a first prescribed value. A latch circuit 51 selectively latches data stored in either of the first buffer BUF1 and second buffer BUF2 synchronously with the first strobe signal STRB1. |
