PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit in which the latency in reading a register is further improved, and a register read method.SOLUTION: A semiconductor integrated circuit 100 includes: a data transfer control unit 2 that includes one or more registers 21; and a processor 1 that reads data values of the registers 21. The data transfer control unit 2 includes a comparison circuit 22 that compares a data value of each of the registers 21 with an expected value that is output by the processor 1. The processor 1 transmits the expected value together with a read command to the data transfer control unit 2 when reading the data value of the register 21. The data transfer control unit 2 refers to a comparison result of the comparison circuit 22 and, if the expected value and the data value of the register 21 match, transmits the data value of the register 21 to the processor 1. |
