Table 16.
1. Grey cells represent Read cycles. The other cells are Write cycles.
2. SA Protection Group Address, BA Any address in the Block, BKA Bank Address, SL Standard Protection Mode Lock bit
3. Addresses are described in
4. During Unlock and Command cycles, if the lower address bits are 555h or 2AAh then the address bits higher than A11
5. A Reset Command must be issued to return to the Read mode.
6. The 4
7. Data is latched on the rising edge of W.
8. The entire command sequence must be entered for each portion of the password.
9. The command sequence returns FFh if the Password Protection Mode locking bit is set.
10. The password is written over four consecutive cycles, at addresses [0-3]
11. A 2µs timeout is required between any two portions of the password.
12. A 10ms delay is required between the 4th and the 5th cycle.
13. A 12ms timeout is required between cycles 4 and 5.
14. Cycle 4 erases all Non-Volatile Modify Protection bits. Cycles 5 and 6 verify that the bits have been successfully cleared
15. DQ1=1 if the Non-Volatile Modify Protection bit is locked, DQ1 = 0 if it is unlocked.
