bits 7 to 0 of the low byte of the SHADOW word like a regular
EEPROM location at address $0FC0 and $0FC1. Do not program
other bits of the high byte of the SHADOW word (location $0FC0);
otherwise some regular EEPROM array locations will not be
visible. At the next reset, the SHADOW values are loaded into the
EEDIVH and EEDIVL registers. They do not require further
initialization as long as the oscillator frequency of the target
application is not changed.
