7. CPU ARCHITECTURE
7.1 Memory Space
A 1M-byte memory space can be accessed. By using a LOCATION instruction, the 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 data areas are mapped to 0F700H-0FFFFH.
(2) When the LOCATION 0FH instruction is executed
Internal data areas are mapped to FF700H-FFFFFH.
