00038  * Revision 1.4  2008/08/22 09:25:34  haraldkipp
00039  * Clock value caching and new functions NutArchClockGet, NutClockGet and
00040  * NutClockSet added.
00041  *
00042  * Revision 1.3  2008/08/11 06:59:58  haraldkipp
00043  * BSD types replaced by stdint types (feature request #1282721).
00044  *
00045  * Revision 1.2  2008/07/08 08:25:05  haraldkipp
00046  * NutDelay is no more architecture specific.
00047  * Number of loops per millisecond is configurable or will be automatically
00048  * determined.
00049  * A new function NutMicroDelay provides shorter delays.
00050  *
00051  * Revision 1.1  2005/07/26 18:42:19  haraldkipp
00052  * First check in
