PRIMARY-VENDOR SPECIFIC EXTENDED QUERY TABLE
Certain flash features and commands are optional. The
Primary Vendor-Specific Extended Query
table specifies this and other similar information.
NOTE:
1.
Future devices may not support the described “Legacy Lock/Unlock” function. Thus bit 3 would have a value
of “0.”
