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

MLX90132.
