* host mode.

|
* the user must enable global interrupts before or shortly after this function is called. In

* enabled at the application's leisure however enumeration will not begin of an attached device
|
||||||
|
* until after this has occurred.
|
||||||
|
*
|
||||||
|
* Calling this function when the USB interface is already initialized will cause a complete USB
|
||||||
|
* interface reset and re-enumeration.
|

|
* \param[in] Mode This is a mask indicating what mode the USB interface is to be initialized to, a value

* from the \ref USB_Modes_t enum.

||||||
|
*
|
||||||
|
* \param[in] Options Mask indicating the options which should be used when initializing the USB
|
||||||
|
* interface to control the USB interface's behaviour. 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
|

* function prototype.

*
|

|
* \note To reduce the FLASH requirements of the library if only fixed settings are 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
