The Program EEPROM on the MC68HC805PV8 is 7936 bytes and is
located from address $2000 to $3EFF. It also holds 16 bytes of user
vectors ranging from $3FF0 to $3FFF. Programming circuitry embedded
in the EEPROM block allows a group of up to four different bytes to be
written or erased simultaneously. These four bytes must be located in
the set of addresses which differ only in the two least significant bits. An
internal charge pump is provided, avoiding the necessity to supply a high
voltage for erase and programming functions. In order to achieve a
higher degree of security for stored data, there is no capability for bulk
or row erase in single chip mode.
