33.4.10 Data Protect Function
(Lock bit disable select bit)
(Ready/busy status flag)
Each block in the flash memory has a nonvolatile lock bit. The lock bit is enabled by setting the FMR13 bit in
the FMR1 register is set to 0 (lock bit enabled). The lock bit can be used to disable (lock) programming or
erasing each block. This prevents data from being written or erased inadvertently. A block status changes
according to the lock bit as follows:
•
•
The lock bit data is set to 0 (locked) by executing the lock bit program command and to 1 (not locked) by
erasing the block. No commands can be used to set only the lock bit data to 1.
The lock bit data can be read using the read lock bit status command.
When the FMR13 bit is set to 1 (lock bit disabled), the lock bit function is disabled and all blocks are not locked
(each lock bit data remains unchanged). The lock bit function is enabled by setting the FMR13 bit to 0 (the lock
bit data is retained).
When the block erase command is executed while the FMR13 bit is set to 1, the target block is erased regardless
of the lock bit status. The lock bit of the erase target block is set to 1 after auto-erasure completes.
Refer to 33.4.11 Software Commands for the details of individual commands.
The FMR13 bit is set to 0 after auto-erasure completes. This bit is also set to 0 if one of the following conditions
is met. To erase or program a different locked block, set the FMR 13 bit to 1 again and execute the block erase
or program command.

Figure 33.6 shows the FMR13 Bit Operation Timing.
When the lock bit data is set to 0: locked (the block cannot be programmed or erased)
When the lock bit data is set to 1: not locked (the block can be programmed and erased)
The FST7 bit in the FST register changes from 0 (busy) to 1 (ready).
An incorrect command is input.
The FMR01 bit in the FMR0 register is set to 0 (CPU mode disabled).
The FMSTP bit in the FM0 register is set to 1 (flash memory stops).
