M68HC11E Family — Rev. 3.2
MOTOROLA
prevents the memory locations from being monitored externally because
single-chip modes do not allow visibility of the internal address and data
buses. Resident programs, however, have unlimited access to the
internal EEPROM and RAM and can read, write, or transfer the contents
of these memories.
An enhanced security feature which protects EPROM contents, RAM,
and EEPROM from unauthorized accesses is available in
MC68S711E9. Refer to
