2.2 Introduction
The CPU08 can address 64 Kbytes of memory space. The memory
map, shown in Figure 2-1, includes:
• 60 Kbytes of FLASH EEPROM
• 2048 bytes of RAM
• 1024 bytes of EEPROM with protect option
• 38 bytes of user-defined vectors
• 224 bytes of monitor ROM
These 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.
