Figure 27.18 Read Lock Bit Status Command Flow
27.3.5.7
27.3.5.8
This command is executed to verify if a specified block in the flash memory is locked. This command is
available when the LBM bit in the FMR0 register is 1 (read by the LBS bit).
To read the LBS bit from the FMR0 register, write 0071h to address FFFFF800h, verify that the FCA bit
in the FMR0 register is 0, then write 00D0h to an even address of the corresponding block.
Read the LBS bit after the RDY bit in the FMSR0 register becomes 1 (ready).
This command is executed to enter read lock bit status mode. This command is enabled when the LBM
bit in the FMR0 register is 0 (read via data bus).
To read the lock bit status of the read block, write 0071h to address FFFFF800h (Refer to Table 27.17).
The status is read in any address of the flash memory.
Execute this command in RAM.
