General Release Specification

MC68HC05RC17 — Rev. 2.0

Memory

2.3.1 ROM

The user ROM consists of 15,920 bytes of ROM located from $0180 to

$3FAF and 16 bytes of user vectors located from $3FF0 to $3FFF.

The burn-in ROM is located from $3FB0 to $3FEF.

Ten of the user vectors, $3FF6 through $3FFF, are dedicated to reset

and interrupt vectors. The six remaining locations — $3FF0, $3FF1,

$3FF2, $3FF3, $3FF4, and $3FF5 — are general-purpose user ROM

locations.

2.3.2 ROM Security

Security has been incorporated into the MC68HC05RC17 to prevent

external viewing of the ROM contents. This feature helps ensure that

customer-developed software remains proprietary.1

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

copying the ROM difficult for unauthorized users.
