The read lock bit status command reads the lock bit state of a specified block.
By writing “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 or not the lock bit of a
specified block is locked. Read the FMR16 bit after the FMR00 bit in the FMR0 register is set to “1” (ready).
Figure 22.13 shows a Flow Chart of the Read Lock Bit Status Command Programming.
