Notes
• All the addresses specified here must be within the range of the data memory area available with each
microcomputer model.
An error results if the input one is not a hexadecimal number or a valid symbol.
Error : invalid value.
An error results if the limit is exceeded.
Error : Data address out of range.
• Write operation is not performed to the read-only address of the I/O area.
• Data in the write-only area cannot be read. If the source area contains write-only address, 0 is written
to the corresponding destination. If the destination area contains read-only address, the data of that
address can not be rewritten. If the source and destination areas contain I/O address of mixed read-
only bits and write-only bits, either read or write operation can be executed for the corresponding
bits.
• An error results if there is an unused area in the specified source or destination area, and no copy
operation will be done.
Error : no mapping area.
• When the contents of the data memory is modified using the dm command, the displayed contents of
the [Data] window are updated automatically.
