ROM Description
E.1
ROM control registers are located in the same place as the 16-byte memory space for Flash control
registers 0x0100-0x010F. There are no EEPROM control registers in a ROM device and register locations
0x0110-0x011F are reserved.
E.1.1
Upon reset the contents of the non-volatile location NVOPT are copied from ROM into ROPT. This
register may be read at any time, but writes have no meaning or effect.
