<p>A host controller is suitable for transferring data in transactions, each transaction being described by a transfer descriptor, and the transactions include split transactions. The transfer descriptor for a split transaction includes a bit which may be set to indicate whether the split transaction is a start split or a complete split transaction, and, once a transaction comprising split transactions has been started by a first split transaction, subsequent split transactions are generated automatically until the transaction is complete.</p> |
