2. To set this bit to 0, first write 1 and then 0 immediately. Disable interrupts and DTC activation between writing 1
3. This bit is set to 0 when the FMR01 bit in the FMR0 register is set to 0 (CPU rewrite mode disabled).

[Conditions for setting to 0]
The FMR13 bit is set to 0 when one of the following conditions is met.
[Condition for setting to 1]
Set to 1 by a program.
writing 0 and writing 1.
and writing 0.
When the FMR13 bit is set to 1 (lock bit disabled), the lock bit is disabled. When the FMR13 bit is set to 0, the
lock bit is enabled. Refer to 31.4.10 Data Protect Function for the details of the lock bit.
The FMR13 bit enables the lock bit function only and the lock bit data does not change. However, when a block
erase command is executed while the FMR13 bit is set to 1, the lock bit data set to 0 (locked) changes to 1 (not
locked) after erasure completes.
