-* ----- -------- -------- -----------------------------------------------
-* 1.00a ecm/sdm  11/11/09 First release
-* 3.07a sgd      07/05/12 Upadted micro sleep function to make use Global Timer
-* 4.2  pkp              08/04/14 Removed unimplemented nanosleep routine as it is not
-*                                                possible to generate timer in nanosecond due to
