Introduction
This section describes the operation of the embedded ROM-1 memory.
Functional Description
The ROM memory physically consists of two independent arrays of 32K
bytes with an additional 52 bytes of user vectors and two bytes of block
protection. The address ranges for the user memory and vectors are:
NOTE:
• $8000–$FDFF
• $FFCC–$FFFF (These locations are reserved for user-defined
interrupt and reset vectors.)
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 difficult for unauthorized users.
