Clarify the operation of IRET instruction. What memory locations comprise the vector for an INT 34 instruction?
Interrupt return (IRET) instruction is used only with hardware or software interrupt service procedures. Whenever an IRET instruction executes, it stores the contents of T and I from the stack. This is essential because it preserves the state of flag bits. If interrupts were enabled before an interrupt service procedure, they automatically re-enabled by IRET instruction as it restores the flag register.
Interrupt Number 20-FF are stored at an address 80 - 3FFH.
