Introduction
The MC68HC08AZ48 can address 48 Kbytes of memory space. It is
basically identical to the MC68HC08AZ60 part except that ROM and
EEPROM size are smaller. The memory map, shown in Figure 1,
includes:
• 48 Kbytes of ROM
• 1536 Bytes of RAM
• 768 Bytes of EEPROM with Protect Option
• 52 Bytes of User-Defined Vectors
• 224 Bytes of Monitor ROM
The following definitions apply to the memory map representation of
reserved and unimplemented locations.
• Reserved — Accessing a reserved location can have
unpredictable effects on MCU operation.
• Unimplemented — Accessing an unimplemented location
causes an illegal address reset if illegal address resets are
enabled.
