33.4.11.6 Read Lock Bit Status Command
This command is used to read the lock bit status of any address in the program ROM area.
When 71h written in the first bus cycle and D0h is written in the second cycle to the starting block address, the
lock bit status of the specified block is stored in the LBDATA bit in the FST register. After the FST7 bit in the
FST register has been set to 1 (ready), read the LBDATA bit.
Figure 33.13 shows the Read Lock Bit Status Flowchart.
