S5U1C63000A MANUAL EPSON 169
(S1C63 FAMILY ASSEMBLER PACKAGE)
dm (data memory move)
Function
This command copies the contents of the specified data memory area to another area.
Format
(1) >dm <address1> <address2> <address3>↵ (direct input mode)
(2) >dm↵ (guidance mode)
Start address ? <address1>↵
End address ? <address2>↵
Destination address ? <address3>↵
>
<address1>: Start address of source area to be copied from; hexadecimal or symbol (IEEE-695 format only)
<address2>: End address of source area to be copied from; hexadecimal or symbol (IEEE-695 format only)
<address3>: Address of destination area to be copied to; hexadecimal or symbol (IEEE-695 format only)
Condition: 0 ≤ address1 ≤ address2 ≤ 0xffff, 0 ≤ address3 ≤ 0xffff
Examples
Format (1)
>dm 200 2ff 280↵ ... Copies data within the range from address 0x200 to address 0x2ff
to the area from address 0x280.
Format (2)
>dm↵
Start address ? 200↵ ... Source area start address is input.
End address ? 2ff↵ ... Source area end address is input.
Destination address 280↵ ... Destination area start address is input.

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 (no such symbol / symbol type error)
An error results if the limit is exceeded.
Error : Address out of range, use 0-0xFFFF
•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.
•When the contents of the data memory is modified using the dm command, the displayed contents of
the [Data] window are updated automatically.
