6. CPU ARCHITECTURE
6.1 Memory Space
A 1M-byte memory space can be accessed. The mapping of the internal data area (special function registers
and internal RAM) can be selected by using the LOCATION instruction. The LOCATION instruction must be
always executed after the reset signal has been deasserted, and must not be used more than once.
(1) When LOCATION 0 instruction is executed
Internal memory
The internal data area and internal ROM area are mapped as follows:
Internal data area : 0FB00H through 0FFFFH
Internal ROM area: 00000H through 07FFFH
External memory
The external memory is accessed in the external memory expansion mode.
(2) When LOCATION 0FH instruction is executed
Internal memory
The internal data area and internal ROM area are mapped as follows:
Internal data area : 0FB00H through FFFFFH
Internal ROM area: 00000H through 07FFFH
External memory
The external memory is accessed in the external memory expansion mode.
