Write with Error Correction
Writes the designated data to the RF Tag beginning from the specified start address, and writes the RF
Tag memory check code and error correction code to the next 5 bytes of memory. Do not change this
code. It is required by the Read with Error Correction command.
Up to 510 bytes (i.e., 255 words) can be specified for one command execution.
• Verification will not be performed if No Verification is set for writing.
• Check the memory capacity of the RF Tag before setting the Processing Address and Number of Processing Bytes. If
the Processing Address and Number of Processing Bytes are not suitable for the RF Tag for which communications
are being performed, the RF Tag Address Error Flag (CIO n+8, bit 13) will turn ON.
• The five bytes of data after the area extending from the Processing Bytes is the check code area. Do not write any
data to the check code area.
• Check the memory capacity of the RF Tag before setting the Processing Address and Number of Processing Bytes. If
the Processing Address and Number of Processing Bytes are not suitable for the RF Tag for which communications
are being performed, the RF Tag Address Error Flag (CIO n+8, bit 13) will turn ON.
