Abstract
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.
