2.3.4 ITS Q-Channel

The ITS has a Q-Channel interface which controls requests from an external clock gating source.

If the ITS is busy, the Q-Channel interface asserts the qdeny signal to deny an external request to gate its clock. When an external request occurs, the interface requests a wakeup by asserting qactive.

The qreqn input is synchronized to the ITS. See A.2 Power control signals.
