* Endpoint Device Queue Head
|

*
|
|
* Device queue heads are arranged in an array in a continuous area of memory
|
|
* pointed to by the ENDPOINTLISTADDR pointer. The device controller will index
|
|
* into this array based upon the endpoint number received from the USB bus.
|
|
* All information necessary to respond to transactions for all primed
|
|
* transfers is contained in this list so the Device Controller can readily
|
|
* respond to incoming requests without having to traverse a linked list.
|
|
*
|
|
* The device Endpoint Queue Head (dQH) is where all transfers are managed. The
|
|
* dQH is a 48-byte data structure, but must be aligned on a 64-byte boundary.
|
|
* During priming of an endpoint, the dTD (device transfer descriptor) is
|
|
* copied into the overlay area of the dQH, which starts at the nextTD pointer
|
|
* DWord and continues through the end of the buffer pointers DWords. After a
|
|
* transfer is complete, the dTD status DWord is updated in the dTD pointed to
|
|
* by the currentTD pointer. While a packet is in progress, the overlay area of
|
|
* the dQH is used as a staging area for the dTD so that the Device Controller
|
|
* can access needed information with little minimal latency.
|
|
*
|
|
* @note
|
|
* Software must ensure that no interface data structure reachable by the
|
|
* Device Controller spans a 4K-page boundary. The first element of the
|
|
* Endpoint Queue Head List must be aligned on a 4K boundary.
