ABSTRACT:
Interrupt circuitry is provided for an MOS integrated circuit microprocessor chip. An input of the microprocessor chip is adapted to having an external interrupt signal applied thereto for interrupting the operation of the microprocessor chip within a digital data processing system. The input is coupled to circuitry which inhibits loading of the next instruction to be executed in response to an interrupt request signal applied to the interrupt request input, and also forces a code into the instruction register in response to the interrupt request signal. The code is substantially similar to the code for a software wait instruction or a software interrupt instruction. Therefore, much of the same circuitry within the microprocessor can be used for executing an interrupt operation, a software wait instruction, or a software interrupt instruction.
