Abstract
An LSI includes an address decoder in which combinations of IP cores and control registers simultaneously accessed according to an operation mode signal are set in advance, so that the plurality of control registers can be accessed with a single system address signal. Therefore, it is unnecessary that the CPU is provided with selection signals whose number is equal to that of the combinations of the control registers. This reduces coding work for operating CPU, reducing work in developing a program of the CPU.
