10.2 Introduction

The user EEPROM consists of 920 bytes of user EEPROM from $0020

to $00BF and $0100 to $03F7, and 8 bytes of user vector EEPROM from

$03F8 to $03FF. The COP reset address is located within the main

EEPROM address space at $03F0. It may be used as a user EEPROM

location and is included in the available user EEPROM space previously

disclosed.

10.3 EEPROM Programming

The MC68HC805K3 user EEPROM and MOR can only be programmed

using the appropriate programming board available from Motorola.

10.4 EEPROM Security

The MC68HC805K3 programmer allows the user to optionally select

EEPROM security such that an attempt to enter any non-user operating

mode will initiate an automatic bulk erasure of all EEPROM locations

including the PEEP. Prior to programming the device, the array is also

bulk erased automatically.
