|
||||
* mode (device or host).
|

*
|

* \param[in] Options Mask indicating the options which should be used when initializing the USB
|
||||
* interface to control the USB interface's behavior. This should be comprised of
|
||||
* a \c USB_OPT_REG_* mask to control the regulator, a \c USB_OPT_*_PLL mask to control the
|
||||
* PLL, and a \c USB_DEVICE_OPT_* mask (when the device mode is enabled) to set the device
|
||||
* mode speed.
|
||||
*
|
||||
* \note To reduce the FLASH requirements of the library if only device or host mode is required,
|
||||
* the mode can be statically set in the project makefile by defining the token \c USB_DEVICE_ONLY
|
||||
* (for device mode) or \c USB_HOST_ONLY (for host mode), passing the token to the compiler
|
||||
* via the -D switch. If the mode is statically set, this parameter does not exist in the
|
||||
* function prototype.
|

* \n\n
|
||||
*
|
||||
* \note To reduce the FLASH requirements of the library if only fixed settings are required,
|
||||
* the options may be set statically in the same manner as the mode (see the Mode parameter of
|
||||
* this function). To statically set the USB options, pass in the \c USE_STATIC_OPTIONS token,
|
||||
* defined to the appropriate options masks. When the options are statically set, this

||||
* parameter does not exist in the function prototype.
