Write Password
On receiving the Write Password command, the LRIS2K uses the data contained in the
request to write the password and reports whether the operation was successful in the
request. The Option_flag is supported.
During the write cycle time, t
Otherwise, the LRIS2K may not correctly program the data into the memory. The t

again by issuing a Lock Password command to re-activate the block protection.
Prior to writing the password for a block, the Write Password command erases the Protect
Status area of the block.
