UFS_FLAGS_DESCRIPTOR enumeration

Description

UFS_FLAGS_DESCRIPTOR describes the different types of flags used by Universal Flash Storage (UFS) descriptors.

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.
