6. CPU ARCHITECTURE
6.1 Memory Space
A 1M-byte memory space can be accessed. By using a LOCATION instruction, mode for mapping internal data
areas (special function registers and internal RAM) can be selected. A LOCATION instruction must always be
executed after a reset, and can be used only once.
(1) When the LOCATION 0 instruction is executed
Internal memory
The table below indicates the internal data areas and internal ROM areas of each product.
Caution The following internal ROM areas, existing at the same addresses as the internal data areas,
cannot be used when the LOCATION 0 instruction is executed:
External memory
External memory is accessed in external memory expansion mode.
(2) When the LOCATION 0FH instruction is executed
Internal memory
The table below lists the internal data areas and internal ROM areas for each product.
External memory
External memory is accessed in external memory expansion mode.
