The instruction will globally enable all associated interrupt events. To execute an interrupt subroutine, a global interrupt must be enabled first.

When entering RUN mode, the initial state is to prohibit interrupts. In RUN mode, the interrupt enable instruction (EI) can be executed to allow all interrupts. Executing the disable interrupt instruction (DI) can disable the interrupt process; However, the activated interrupt events continue to queue up.
