Note: Data bus bit 6.
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 bus(D6).
Figure 1.26.7 shows an example of a read lock bit program flowchart.
