4.2 Introduction
This section describes the 5,632 bytes of ROM (read-only memory).
4.3 Functional Description
These addresses are user ROM locations:
$E600–$FBFF (user memory; 5,632 bytes)
NOTE:
$FFF0–$FFFF (user vectors; 16 bytes)
A security feature prevents viewing of the ROM contents.¹
1. No security feature is absolutely secure. However, Freescale’s strategy is to make reading or
copying the ROM contents difficult for unauthorized users.
