6.4 Data Transfer Instructions
6.4.4 Character string transfers ($MOV(P))
(3) If the "00H" code is being stored at lower bytes of +n, "00H" will be stored at both the
higher bytes and the lower bytes of +n.
Operation Error
(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and
an error code is stored into SD0.
• There is no "00 H" code stored between the device number designated by and the
relevant device. (Error code: 4101)
• The entire character string linked from the device number designated by to the final
device number of the relevant device cannot be stored. (Error code: 4101)
• The character string of exceeds 16383 characters. (Error code: 4101)
Program Example
(1) The character string data stored in D10 to D12 is transferred to D20 to D22 when X0 goes
ON.
