s The second Bus Write cycle latches the block
address.
The lock status can be monitored for each block
using the Read Electronic Signature command.
Locked-Down blocks revert to the locked (and not
locked-down) state when the device is reset on
power-down. Table. 13 shows the Lock Status af-
ter issuing a Block Lock-Down command. Refer to
the section, Block Locking, for a detailed explana-
tion and Appendix C, Figure 28, Locking Opera-
tions Flowchart and Pseudo Code, for a flowchart
