■ Changes to the BOOTCFG register are effective after the next reset.
■ The NW bit in the USER_REG0, USER_REG1, USER_REG2, USER_REG3, and BOOTCFG
registers is cleared when the register is committed. Once this bit is cleared, additional changes
to the register are not allowed.
Important: After being committed, these registers can only be restored to their factory default values
by performing the sequence described in “Recovering a "Locked"
Microcontroller” on page 185. The mass erase of the main Flash memory array caused
by the sequence is performed prior to restoring these registers.

Register Map
Table 6-3 on page 308 lists the ROM Controller register and the Flash memory and control registers.
The offset listed is a hexadecimal increment to the register's address. The Flash memory register
offsets are relative to the Flash memory control base address of 0x400F.D000. The ROM and Flash
memory protection register offsets are relative to the System Control base address of 0x400F.E000.
