See osccal.h for a documentation + of the API. + +osctune.h + This header file contains a code snippet for usbconfig.h. With this code, + you can keep the AVR's internal RC oscillator in sync with the USB frame + clock. This is a continuous synchronization, not a single calibration at + USB reset as with osccal.c above.
