EESEC — EEPROM security enable bit.
EESEC enables the EEPROM security function. Setting EESEC
prevents program/erase access to locations $8F0 – $8FF of the
EEPROM array and to the EEACR/EENVR configuration registers.
See MC68HC08AZ32 EEPROM Security on page 45

Extra care should be exercised when selecting mask option
