Members

bLength

Specifies the size, in bytes, of this descriptor.

bDescriptorIDN

Specifies the Configuration Descriptor Type Identifier. This descriptor will have a value of UFS_DESC_CONFIGURATION_IDN.

bConfDescContinue

Specifies if a device's configuration descriptor continue feature is enabled.

bBootEnable

Specifies if a device's boot feature is enabled.

bDescrAccessEn

Enables access to the Device Descriptor after the partial initialization phase of the boot sequence.

bInitPowerMode

Specifies the power mode after device initialization or hardware reset.

bHighPriorityLUN

bHighPriorityLUN configures the high priority logical unit.

bSecureRemovalType

Configures the secure removal type.

bInitActiveICCLevel

Configures the ICC level in Active mode after device initialization or hardware reset.

wPeriodicRTCUpdate[2]

Specifies the frequency and method of real-time clock updates.

Reserved2[1]

Reserved for future use.

bRPMBRegionEnable

Specifies if Replay Protected Memory Blocks (RPMB) are enabled.

bRPMBRegion1Size

Specifies the size of RPMB region 1.

bRPMBRegion2Size

Specifies the size of RPMB region 2.

bRPMBRegion3Size

Specifies the size of RPMB region 3.

UnitConfig[UFS_MAX_NUM_LU]

Contains the configurable parameters of the unit descriptor.
