Abstract
PURPOSE: To carry out the process of interruption in a high speed and thus prevent the lowering of the processing capacity, by repeating the reading of the contents of the next interruption state register corresponding to the interruption state information stored.
CONSTITUTION: The interruption information Sa1WSa64 are latched by the interruption registers IR1WIR16, latched by the interruption state registers ISR1WISR4 via OR circuits ORa1WORa16, and latched furthermore by the interruption state rgister ISR via the OR circuits ORb1WORb4 respectively. Then the interruption signal Sd is produced with "0" of the output of the NOR circuit NOR. The search for the factor of the interruption is done by repeating the reading the contents of te next interruption state register corresponding to the interruption state information stored after reading the contents of the register ISR. Thus the process of interruption can be carried out in a high speed, and accordingly the lowering of the processing capacity can be avoided.
