Figure 25.12 Read Lock Bit Status Command

25.3.5.8 Read Lock Bit Status Command

The read lock bit status command reads the lock bit state (the lock bit data) of a specified block.

By writing command code "xx7116" in the first bus cycle and "xxD016" to the highest-order even ad-

dress 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 25.12 shows a flow chart of the read lock bit status command programming.
