*       ConfigTargetSettings()
*
*  Function description
*    Called before InitTarget(). Mainly used to set some global DLL variables to customize the
*    normal connect procedure. For ARM CoreSight devices this may be specifying the base
*    address of some CoreSight components (ETM, ...) that cannot be auto-detected by J-Link
*    due to erroneous ROM tables etc. May also be used to specify the device name in case
*    debugger does not pass it to the DLL.
*
*  Return value
*    >= 0:  O.K.
*     < 0:  Error
*
*  Notes
*    (1)May not, under absolutely NO circumstances, call any API functions that perform target communication.
*    (2)Should only set some global DLL variables.
