/* HccaDoneHead: When the HC reaches the end of a frame and its deferred
* interrupt register is 0, it writes the current value of its HcDoneHead to
* this location and generates an interrupt.
*
* The LSB of HCCADoneHead may be set to 1 to indicate that an unmasked
* HcInterruptStatus was set when HccaDoneHead was written.
