Members
bLength
Specifies the length, in bytes, of this descriptor.
bDescriptorIDN
Specifies the type of the descriptor. This descriptor will have a value of UFS_DESC_UNIT_IDN.
bUnitIndex
Specifies unit index
bLUEnable
Specifies if the logic unit number (LUN) is enabled. If bLUEnable is equal to 0x00, the logical unit is disabled.
bBootLunID
bLUWriteProtect
Specifies if the logical unit is write-protected. Contains one of the following values:
Value | Description |
---|---|
0x00 | The logical unit is not write protected. |
0x01 | The logical unit is write protected. |
0x02 | The logical unit is permanently write protected. |
bLUQueueDepth
Specifies the logical unit queue depth. Can be any value from 0x00 to 0xff.
bPSASensitive
Specifies if the logical unit is sensitive to soldering. Contains one of the following values:
Value | Description |
---|---|
0x00 | The logical unit is not sensitive to soldering. |
0x01 | The logical unit is sensitive to soldering. |
bMemoryType
Specifies the desired memory type. Equal to 0x0F.
Reserved
Reserved for future use.
Reserved for future use.
bLogicalBlockSize
Specifies the logical block size of the descriptor.
qLogicalBlockCount[8]
Specifies the total number of addressable logical blocks in the logical unit.
dEraseBlockSize[4]
Specifies the erase block size.
bProvisioningType
Specifies the provisioning type.
qPhyMemResourceCount[8]
Specifies the total physical memory resources available in the logical unit.
Reserved2[3]
Requirements
Requirement | Value |
