Bits[7:4] are loaded at reset from the EEPROM SHADOW word.
The bits 5 and 4 are reserved for test purposes. These locations in
SHADOW word should not be programmed otherwise some locations of
regular EEPROM array will not be more visible.
NOBDML — Background Debug Mode Lockout Disable
NOSHW — SHADOW Word Disable
Bit 6 from high byte of SHADOW word should not be programmed in
order to have the full EEPROM array visible.
Loaded from SHADOW word at reset.
Read anytime. Write anytime in special modes (SMODN=0).
Loaded from SHADOW word at reset.
Read anytime. Write anytime in special modes (SMODN=0).
When NOSHW cleared, the regular EEPROM array bytes at address
$0FC0 and $0FC1 are not visible. The SHADOW word is accessed
instead for both read and program/erase operations. Bits[7:4] from
the high byte of the SHADOW word, $0FC0, are loaded to
EEMCR[7:4]. Bits[1:0] from the high byte of the SHADOW word,
$0FC0,are loaded to EEDIVH[1:0]. Bits[7:0] from the low byte of the
SHADOW word, $0FC1,are loaded to EEDIVL[7:0]. BULK
program/erase only applies if SHADOW word is enabled.
