Abstract
Herein disclosed is an information processing apparatus having a synchronous storage and the synchronous storage which can resume an operation continuing from before an interruption without hindrance even after a series of read/write operations have been interrupted and a read/write of internal condition values has been performed in a scanning operation or the like. The information processing apparatus successively selects information stored in address backup registers in two stages and data backup registers in two stages and outputs the selected information to the synchronous storage when a normal operation is resumed, thereby restoring an address data register, a data input register and a data output register to the same conditions as before the interruption of the normal operation. This invention is applicable to a synchronous storage accessible in synchronism with a system clock and an information processing apparatus having such synchronous storage.
