Explanation:
Detailed explanation-1: -The address of the service routine in vectored interrupt is hard-wired and in non-vectored interrupts, the address of the service routine needs to be supplied extremely by the device. The DI interrupt instruction is used to disable the interrupt and the EI interrupt instruction is used to enable the instruction.
