26.3.2.7
The read lock bit status command reads a lock bit status of a given block.
By writing the command code xx71h in the first bus cycle and xxD0h to the highest-order even address of a
block in the second bus cycle, the FMR16 bit in the FMR1 register stores information on whether the lock bit of
the block is locked or not. Read the FMR16 bit after the FMR00 bit in the FMR0 register becomes 1 (ready).
Figure 26.12 shows a flow chart of read lock bit status command.
