The CPU08 can address 64K-bytes of memory space. The memory
map, shown in
Figure
•
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
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.
