2.2 Introduction
The CPU08 can address 64 Kbytes of memory space. The memory
map, shown in Figure 2-1, includes:
• 48,128 bytes of FLASH memory
• 1,024 bytes of random-access memory (RAM)
• 26 bytes of user-defined vectors
• 512 + 470 bytes of monitor ROM
2.3 Unimplemented Memory Locations
Accessing an unimplemented location can cause an illegal address
reset if illegal address resets are enabled. In the memory map
(Figure 2-1) and in register figures in this document, unimplemented
locations are shaded.
