三星ARM9系列CPU SC32442的USB下载的测试程序的源代码

/**************************************************************
 NAME: option.h
 DESC: To measuure the USB download speed, the WDT is used.
       To measure up to large time, The WDT interrupt is used.
 HISTORY:
 Feb.20.2002:Shin, On Pil: Programming start
 Mar.25.2002:purnnamu: S3C2400X profile.c is ported for S3C2442X.
