AUTO DATA FILL (AF)
For AUTO DATA FILL, the ID Controller waits for a Data Carrier to approach and then fills Data Carrier
memory with the specified number of write bytes from the start write address specified in the
command.
The ID Controller will return a response to the host device when communications with the Data Carrier
have been completed.
Data will also be written to write-protected areas of the Data Carrier. Be sure that there is no important data in the write
area before executing this command.

2: Read/Write Head 2
Specifies the first address to which to write data to the Data Carrier as a four-digit hexadecimal
number.
Specifiable range: 0000H to FFFFH
When specifying in odd bytes, this writes the 1 digit prior to the designated data for ASCII code
specification, or the 2 digits of the designated data for hexadecimal specification, to the last 1 byte
of data in the Data Carrier.
Specifiable range: 01H to FFH, 00H (The maximum of 256 bytes will be written if 00H is specified.)
The data to write to Data Carrier memory.
• ASCII specification: Specify 2 bytes.
• Hexadecimal code specification: Specify 4 bytes.
