Command (7)
Command (7)
This command requests a transfer of a single sector of data from the host. Table 11-6 defines the
content of this sector of information. If the password selected by Word 0 matches the password
previously saved by the device, the device disables the lock mode. This command does not change the
Master password that may be reactivated later by setting a User password.
TABLE 11-6: S
This command is issued immediately before the Security-Erase-Unit command to enable device
erasing and unlocking. This command prevents accidental erasure of the data in the flash media.
