摘要 <p>PROBLEM TO BE SOLVED: To permit transition from a normal operation mode to a low power consumption mode at a state that a program is made to be resident in a nonvolatile memory. SOLUTION: When an instruction fetched by an instruction fetch unit 9 is a first instruction to instruct transition from the normal operation mode to the low power consumption mode in a CPU 24, the first instruction is executed despite that the nonvolatile memory is transited to a self-refresh mode by executing a second instruction fetched by an instruction fetch means immediately after the first instruction before first instruction and executing the first instruction after that and the transition from the normal operation mode to the low power consumption mode is possible at the state that the program is made to be resident in the nonvolatile memory.</p>
