All interrupt requests must pass through the PIC’s interrupt request register (IRR) and interrupt mask register (IMR). If put in service, the appropriate bit of the in-service (IS) register is set.

(a) Simultaneous interrupt requests arrive on IR4 and IR6. IR4 has highest priority and its IS bit is set as the IR4 service routine is put in service. (b) The IR4 service routine issues a rotate-on-nonspecific-EOI command, resetting IS4 and assigning it lowest priority. IR6 is now placed in service. (c) The IR6 service routine issues a rotate-on-nonspecific-EOI command, resetting IS6 and assigning it lowest priority.
