Constants

 
UFS_Reserved_00
Reserved for future use.
UFS_fDeviceInit
Indicates the device initialization is in progress.
UFS_fPermanentWPEn
Indicates permanent write protection is enabled.
UFS_fPowerOnWPEn
Indicates power on write protection is enabled.
UFS_fBackgroundOpsEn
Indicates the device is permitted to run background operations.
UFS_fDeviceLifeSpanModeEn
Indicates Device Life Span Mode is enabled.
UFS_fPurgeEnable
Indicates Purge Operation is enabled.
UFS_fRefreshEnable
Initiate a refresh operation by setting UFS_fRefreshEnable to 0x01 and interrupt it by clearing UFS_fRefreshEnable to 0x00.
UFS_fPhyResourceRemoval
Indicates that the dynamic capacity operation occurs on the device's EndPointReset or a hardware reset. The host cannot reset this flag.
UFS_fBusyRTC
Indicates the device is executing internal operation related to Real Time Clock.
UFS_Reserved_0A
Reserved for future use.
UFS_fPermanentlyDisableFwUpdate
Indicates the UFS device will permanently disallow future firmware updates to the Universal Flash Storage (UFS) device.
UFS_Reserved_0C
Reserved for the Unified Memory Extension standard.
UFS_Reserved_0D
Reserved for the Unified Memory Extension standard.
UFS_fWriteBoosterEn
Set the UFS_fWriteBoosterEn flag to one to enable the WriteBooster feature.
UFS_fWriteBoosterBufferFlushEn
The UFS_fWriteBoosterBufferFlushEn flag enables the flush operation. When UFS_fWriteBoosterBufferFlushEn is set to one, the device flushes the WriteBooster buffer.
UFS_fWriteBoosterBufferFlushDuringHibernate
The UFS_fWriteBoosterBufferFlushDuringHibernate enables the flush operation during device hibernate. The device does a WriteBooster buffer flush operation whenever the link enters in the hibernate state.
UFS_Reserved_11
Reserved for future use.
