摘要： A microprocessor having an instruction prefetch function includes a storage circuit in which an instruction externally supplied to the microprocessor via an external interface is stored, a first latch circuit which latches a write address value of the storage circuit in response to an interrupt signal externally supplied to the microprocessor, and an internal interrupt signal outputting circuit which compares a read address value of the storage circuit indicating the instruction stored in the storage circuit with the write address value supplied from the first latch circuit and which generates the internal interrupt signal only when the read address value and the write address value coincide with each other. The microprocessor processes an interrupt process in response to the internal interrupt signal.

摘要： A central processing unit (CPU) carries out selected reset interruption processing by using a vector address preset in accordance with an interruption source to generate an address to a data table whose contents are used to initialize selected registers. In this manner, the CPU can be reset without having first stored the processing state of the CPU in response to a reset interrupt request, without the need for extensive dedicated reset hardware, and with the ability to select desired reset values that can differ as between different interrupts and can be changed from time to time.
