7.1 Memory Space
A memory space of 1 MB can be accessed. Mapping of the internal data area (special function registers and
internal RAM) can be specified by the LOCATION instruction. The LOCATION instruction must always be executed
after reset cancellation, and must not be used more than once.
(1) When LOCATION 0H instruction is executed
Internal memory
The internal data area and internal ROM area are mapped as follows:
Part Number
Internal Data Area
Internal ROM Area
μ
