Memory Map
2.1 Introduction
The CPU08 can address 64K bytes of memory space. The memory map, shown in Figure 2-1, includes:
• 60K Bytes of FLASH EEPROM
• 2048 Bytes of RAM
• 1024 Bytes of EEPROM with Protect Option
• 52 Bytes of User-Defined Vectors
• 256 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.
• Unused — These locations are reserved in the memory map for future use, accessing an unused
location can have unpredictable effects on MCU operation.
• Unimplemented — Accessing an unimplemented location can cause an illegal address reset
(within the constraints as outlined in the Chapter 9 System Integration Module (SIM)).
