8.3 Register Map
Table 8-6 on page 636 lists the ROM Controller register and the Flash memory 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 EEPROM registers
are relative to the EEPROM base address of 0x400A.F000. The ROM control and Flash memory
protection register offsets are relative to the System Control base address of 0x400F.E000.
