The SHADOW byte can be protected from being programmed or erased
by setting the SHPROT bit of EEPROT register.
Bits[7:4] are loaded at reset from the EEPROM SHADOW byte.
The bits 5 and 4 are reserved for test purposes. These locations in
SHADOW byte should not be programmed otherwise some locations of
regular EEPROM array will be no more visible.
NOBDML — Background Debug Mode Lockout Disable
NOSHB — SHADOW Byte Disable
The bit 6 in SHADOW byte should not be programmed in order to have
the full EEPROM array visible.
Loaded from SHADOW byte at reset.
Read anytime. Write anytime in special modes (SMODN=0).
Loaded from SHADOW byte at reset.
Read anytime. Write anytime in special modes (SMODN=0).
When NOSHB cleared, the regular EEPROM array byte at address
$0FC0 is no more visible. The SHADOW byte is accessed instead for
both read and program/erase operations. BULK, ODD and EVEN
program/erase only applies if SHADOW byte is enabled.
