Reset Behavior
Reset
Each host controller has an independent rest associated with it. Control of these resets is accessed through the Reset Register.
Each host controller and DMA will be in reset state once powered off and require SW (BIOS or driver) to write into specific reset register to bring the controller from reset state into operational mode.
