NAME: PowerOff.c
DESC: Power Off mode test
HISTORY:
03.21.2002:purnnamu: first release for S3C2410X
05.10.2002:SOP RTC Name Change (DAY,DATE)
08.24.2002:purnnamu
LCDVFn is connected the analog circuit in LCD.
So, this signal should be output L.
01.27.2003:SOP Reconfiguration GPG10 Output -> Input
Power-Off mode is fixed SD Card increment current (4mA -> 35mA)
02.25.2003:SOP Reconfiguration GPF3/GPG0,1,4,5,10 Pull-Up Disable -> Enable
05.06.2003:SOP
06.13.2003:SOP
