6.5.3 ABxF Command 06H: Write

DESCRIPTION

Command 06H writes data to an RFID tag.

DISCUSSION

The Write command is used to write segments of data to contiguous areas of tag memory. It is capable of addressing 1 kByte of the read/write address space of a tag in a single command. The BlockWrite command requires as parameters the start address, the number of bytes to be written, and the data to be written to the RFID tag. If the write range exceeds the last tag address, the controller returns an invalid format error message (error code 21H).
