CHAPTER 3 CPU ARCHITECTURE
3.1 Memory Space
The µPD784938 can access a 1-Mbyte memory space. The mapping of the internal data area (special function registers and
internal RAM) depends on the LOCATION instruction. A LOCATION instruction must be executed after reset release, and can
only be used once.
The program after reset release must be as follows:
RSTVCT CSEG AT 0
DW
RSTSTRT
to
INITSEG CSEG BASE
RSTSTRT: LOCATION 0H; or LOCATION 0FH
