Suppose during an execution of an instruction, the Stack Pointer register had the value 000Ah. After that an interrupt occurred and 8086 started servicing the interrupt after completing mandatory procedures. The Interrupt Vector (IV) of an Interrupt Service Routine (ISR) is B7D72.. The segment address of this IV is B021h and segment address is stored in the memory location 0009Eh and 0009FH. (Must show all calculations) a. What is the value of SP when the ISR is being serviced? ' b. What is the value of IP/Offset? c. What is the Interrupt Type?
