PROBLEM TO BE SOLVED: To provide a microcomputer device which can appropriately mediate an interruption processing from a plurality of peripheral I/O circuits and can change an appropriate clock and the number of access cycles with respect to the appropriate peripheral I/O circuits and a peripheral memory, and which is adjusted to the clock in accordance with the content of the interruption processing. SOLUTION: An interruption controller circuit 2 is provided with means receiving information PRI1 to 3 on interruption priority from the peripheral I/O circuit 3-13-3. Interruption priority is dynamically varied and the clock CLK to CPU 1 is varied by priority information PRI1 to 3. Then, the peripheral I/O circuit 3-13-3 can be accessed at a bus cycle fitted to the clock CLK. |
