A URBD is linked to a EP Queue Head, which is entered in either the

execution, some or all of its transactions may be executed. After

execution, the state of the URBD is updated. The URBD may be retired if all
|
||||
its transactions are complete or if an error occurred. Otherwise, it
|
||||
remains in the schedule so more transactions can be executed later.

\brief This function does the setup for a data transfer for a host channel and

|
||||
Slave mode, the caller must ensure that there is sufficient space in the
|
||||
request queue and Tx Data FIFO.
|
||||
|
||||
For an OUT transfer in Slave mode, it loads a data packet into the
|
||||
appropriate FIFO. If necessary, additional data packets will be loaded in
|
||||
the Host ISR.
|
||||
|
||||
For an IN transfer in Slave mode, a data packet is requested. The data
|
||||
packets are unloaded from the Rx FIFO in the Host ISR. If necessary,
|
||||
additional data packets are requested in the Host ISR.
|
||||
|
||||
For a PING transfer in Slave mode, the Do Ping bit is set in the HCTSIZ
|
||||
register along with a packet count of 1 and the channel is enabled. This
|
||||
causes a single PING transaction to occur. Other fields in HCTSIZ are
|
||||
simply set to 0 since no data transfer occurs in this case.
|
||||
|
||||
For a PING transfer in DMA mode, the HCTSIZ register is initialized with
|
||||
all the information required to perform the subsequent data transfer. In
|
||||
addition, the Do Ping bit is set in the HCTSIZ register. In this case, the

controller performs the entire PING protocol, then starts the data

transfer.
