 * $Log: timer.h,v $
 * Revision 1.4  2006/09/29 12:45:35  haraldkipp
 * Include clock configuration.
 *
 * Revision 1.3  2006/08/31 18:59:50  haraldkipp
 * Added support for the AT91SAM9260. We now determine between processor and
 * master clock. A new API function At91GetMasterClock() had been added to
 * query the latter.
