• Description: M68hc08 Family Of 8-bit Microcontroller Units Mcus
• Manufacturer: Freescale Semiconductor, Inc

Read-Only Memory (ROM)
2.7 Read-Only Memory (ROM)
The ROM memory is intended primarily for program storage.
Consult
Table 1-1. Summary of Device Variations
for ROM memory sizes available and reference
Figure 2-1
for user program ROM locations.
Forty-eight bytes of user vectors, $FFD0–$FFFF, are dedicated to user-defined reset and interrupt
vectors, not all 48 bytes are used as interrupt vectors for this device. See
Table 2-1
for actual vectors used
on this MCU.
Security has been incorporated into the MC68HC08QY/QT Family to prevent external viewing of the ROM
contents. This feature ensures that customer-developed software remains proprietary. No security feature
is absolutely secure. However, Freescale’s strategy is to make reading or copying the ROM difficult for
unauthorized users.
