+ \brief This function trigger a data transfer for a host channel and
+ starts the transfer.
+
+ 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 _core_if Pointer of core_if structure
+ \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
+ to reflect the final xfer_len value.

+ ** FILE NAME : ifxusb_regs.h
+ ** PROJECT : IFX USB sub-system V3
+ ** MODULES : IFX USB sub-system Host and Device driver
+ ** SRC VERSION : 1.0
+ ** DATE : 1/Jan/2009
+ ** AUTHOR : Chen, Howard
+ ** DESCRIPTION : This file contains the data structures for accessing the IFXUSB core
+ ** 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 Global 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.
