The ePort isolation unit blocks new bus traffic and waits for outstanding bus traffic to complete. This is normally done prior to the power shutdown of a power domain or island. Isolation might also be useful for security and safety.

When traffic is quiescent, the isolation unit asserts an interrupt so the firmware can take further action.
