Suppose that the interrupt processing method of is to store the breakpoint in the address of 00000Q unit, and fetch the instruction from the 77777Q unit (that is the first instruction of the interrupt service routine) and execute it. Write the micro-operations sequence that completes this function.19. The 8085 microprocessor respond to the presence of an interrupt a. As soon as the trap pin becomes ‘LOW’ b.

Assume that data memory is all zeros and that the processor's registers have the following values at the beginning of the cycle in which of the instruction word is fetched: (See image attached) What is the new PC address after this instruction is executed? Highlight the path through which this value is determined?
