Interrupt structure of 8085 microprocessor: 8085 IC has six pins from PIN 6 to PIN 11, reserved for interrupts these are :  TRAP, RST 7.5, RST 6.5, RST 5.5 and INTR. PIN 11 is the interrupt acknowledgement (INTA’) that is generated by the 8085 processor in response to the different interrupts that arrive at the interrupt pin.   Figure shows the interrupt structure of 8085 microprocessor.  Interrupt priority is shown by the decimal numbers on the extreme left of the figure. As can be see that TRAP has the higher priority marked by digit 1 and INTR has the least priority marked by digit 5 on the left of figure. IVT (Interrupt vector table): IVT contains the interrupt service routine addresses Table-1 (IVT interrupt[t vector
