* Description:
|
|
* If USB is supported and the board supports a pullup via GPIO (for USB software
|
|
* connect and disconnect), then the board software must provide kinetis_usbpullup.
|
|
* See include/nuttx/usb/usbdev.h for additional description of this method.
|
|
* Alternatively, if no pull-up GPIO the following EXTERN can be redefined to be
|
|
* NULL.
