stop.c

samsung 最新芯片2450 的测试程序.

/***************************************************************

  NAME: stop.c
  DESC: Stop mode test(I/O current measure + ...)
  HISTORY:
  08.24.2002:purnnamu
	LCDVFn is connected the analog circuit in LCD. 
	So, this signal should be output L.
  05.xx.2003:DonGo modifid for 2442X, Power-off -> Sleep. naming change.
  12.04.2006:grmoon
  	- S3C2443 GPIO configuration setup
  10.31.2007: SKY
  	- Modified for 2450
