EE[3:0] — EEPROM Mapping Bits
NOSEC — Security Disable Bit
NOCOP — COP System Disable Bit
EE[3:0] apply only to MC68HC811E2 and allow the 2048 bytes of
EEPROM to be remapped to any 4-Kbyte boundary. See
NOSEC is invalid unless the security mask option is specified before
the MCU is manufactured. If the security mask option is omitted
NOSEC always reads 1. The enhanced security feature is available
in the MC68S711E9 MCU. The enhancement to the standard security
feature protects the EPROM as well as RAM and EEPROM.

0 = Security enabled
1 = Security disabled
1 = COP disabled
