Figure 1.189. Timing for disabling the lock bit
8. Lock Bit Program Command
This command writes "0" (lock) for the lock bit of the specified block. Figure 1.187 shows the lock bit program timing.
To execute the lock bit program command:
(1) Transfer the "77
(2) Transfer addresses A
(3) Transfer the verify command code "D0
lock bit of the specified block. Write the highest address of the specified block for addresses A
The lock bit status can be read with the read lock bit status command. Refer to the data protection function for more
details about the lock bit function and reset procedure.
9. Lock Bit Enable Command
This command enables the lock bits for all blocks. The command code "7A
transmission. This command only enables the lock bit function; it does not set the lock bit itself. Figure 1.188 shows the
lock bit enable timing.
10. Lock Bit Disable Command
This command disables the lock bit for all blocks. The command code "75
transmission. This command only disables the lock bit function; it does not set the lock bit itself. However, if an
erase command is executed after executing the lock bit disable command, all "0" (locked) lock bit data is set to "1"
(unlocked) after the erase operation ends. Figure 1.189 shows the lock bit disable timing. After reset the lock bit is
always enabled.
