option.h

S3C2440+SM501在wince环境下的应用！

/**************************************************************
 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 S3C2440X.
 Jan.E.2004:DonGo: Modified for S3C2440a.
