Security sequence address range:$FFF6$FFFD

Notes:
1. Some mask sets not contain this feature
2. Not applied for remapped MC68HC11A8 and not possibility
to modify BROT for early (Monitor-debugger) versions.
3. See specification for mask remapped devices
4. Device has a special security option which prevents
program/erase access to memory locations $08F0 to $08FF.
This security function is enabled by programming the
CON0 bit in the EENVR to 0. Non secure locations:($0800$08EF)
5. Device has a special security option which prevents
program/erase access to memory locations $06F0 to $06FF.
This security function is enabled by programming the
CON0 bit in the EENVR1 to 0. Non secure locations:($0600$06EF)
6. EEPROM Size depend on device mask set
