2.2 Introduction
The CPU08 can address 64K-bytes of memory space. The memory
map, shown in Figure 2-1, includes:
32, 256 bytes of user FLASH memory
512 bytes of EEPROM
1024 bytes of random-access memory (RAM)
48 bytes of user-defined vectors
307 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.
