Command frame
The content of the data included in the frame of a communication request, and the response from the
MLX90129 to the base-station depends on the command opcode. The meaning of the flags, the equation of
the CRC, the description of the Start-Of-Frame, the End-Of-Frame and the unique identifier number (UID),
the meaning of the error codes… are included in the standard ISO-15693 layers 2 and 3.
Request format for ISO15693 commands:
