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 26, Locking Opera-
tions Flowchart and Pseudo Code, for a flowchart
for using the Lock-Down command.
Table 5. Standard Commands
Note: 1. X = Don’t Care, WA=Word Address in targeted bank, RD=Read Data, SRD=Status Register Data, ESD=Electronic Signature Data,
QD=Query Data, BA=Block Address, BKA= Bank Address, BBKA= Bottom Bank Address, PD=Program Data, PRA=Protection
Register Address, PRD=Protection Register Data, CRD=Configuration Register Data.
2. Must be same bank as in the first cycle. The signature addresses are listed in Table 6.
