Detailed explanation-1: -EI instruction is used for the enable the interrupt system of the 8085 processor. DI instruction is used for the disable the interrupt system of the 8085 processor.
Detailed explanation-2: -DI(Disable Interrupt):-The interrupt enable flip-flop is reset and all the interrupts except the TRAP are disabled. No flags are affected. 4. EI(Enable Interrupt):-The interrupt enable flip-flop is set and all interrupts are enabled.
Detailed explanation-3: -Interrupt instructions include EXIT, SIGNAL, CALL, and RETURN. Instructions that interrupt the flow of a program can cause the program to: End (EXIT)
Detailed explanation-4: -Enable Interrupt (EI) – The interrupt enable flip-flop is set and all interrupts are enabled following the execution of next instruction followed by EI. No flags are affected. After a system reset, the interrupt enable flip-flop is reset, thus disabling the interrupts.
