+

+  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.

+  \param _ifxhc Information needed to initialize the host channel. The xfer_len
+  value may be reduced to accommodate the max widths of the XferSize and

+ \brief A URB Descriptor (URBD) holds the state of a bulk, control,
+  interrupt, or isochronous transfer. A single URBD is created for each URB
+  (of one of these types) submitted to the HCD. The transfer associated with
+  a URBD may require one or multiple transactions.
+
+  A URBD is linked to a EP Queue Head, which is entered in either the
+  isoc, intr or non-periodic schedule for execution. When a URBD is chosen for
+  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.

+  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.
+
+  @param _ifxhc Information needed to initialize the host channel. The xfer_len
+  value may be reduced to accommodate the max widths of the XferSize and
+  PktCnt fields in the HCTSIZn register. The multi_count value may be changed

+ **                     registers.
+ **                     The application interfaces with the USB core by reading from and
+ **                     writing to the Control and Status Register (CSR) space through the
+ **                     AHB Slave interface. These registers are 32 bits wide, and the
+ **                     addresses are 32-bit-block aligned.
+ **                     CSRs are classified as follows:
+ **                     - Core Global Registers
+ **                     - Device Mode Registers
+ **                     - Device Global Registers
+ **                     - Device Endpoint Specific Registers
+ **                     - Host Mode Registers

+ **                     - Host Port CSRs
+ **                     - Host Channel Specific Registers
+ **
+ **                     Only the Core Global registers can be accessed in both Device and
+ **                     Host modes. When the USB core is operating in one mode, either
+ **                     Device or Host, the application must not access registers from the
+ **                     other mode. When the core switches from one mode to another, the
+ **                     registers in the new mode of operation must be reprogrammed as they
+ **                     would be after a power-on reset.
