7 MEMORY ORGANIZATION
The Central Processing Unit (CPU) manipulates operands in three memory spaces as follows (see Fig.5):
16 kbytes internal resp. 64 kbytes external Program Memory
512 bytes internal Data Memory Main-and Auxiliary RAM
up to 64 kbytes external Data Memory (with 256 bytes residing in the internal Auxiliary RAM).
