6.6.1 Support of extended frames
In reader mode it is possible to receive up to 528 bytes of frame data. The extended size is included in the
command code as follows:
Figure 10: Coding of Length of extended frames
Consequently, the
ResultCode
returned depends on the length of the decoded frame received by the
MLX90130.
