Read Lock Bit Status Command (7116)

By writing the command code “7116” in the first bus cycle and then the block address of a flash

memory block in the second bus cycle that follows, the system reads out the status of the lock bit of

the specified block on to the data (D6).

Figure 1.26.7 shows an example of a read lock bit program flowchart.
