4.2 Introduction

This section describes the 8 KBytes of read-only memory (ROM) and 16

bytes of user vectors.

4.3 Functional Description

An unprogrammed or erased location reads as $00. These addresses

are user ROM locations:

•

$DE00–$FDFF

•

$FFF0–$FFFF (These locations are reserved for user-defined

interrupt and reset vectors.)

NOTE:

A security feature prevents viewing of the ROM contents.1

1. No security feature is absolutely secure. However, Motorola’s strategy is to make reading or

copying the ROM contents difficult for unauthorized users.
