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.
