Get Maximum Data Speed (GETMXDS)

The Controller uses the Direct GETMXDS CCC to read the maximum data speed that the Target supports when it sets the BCR0 bit (device is speed-limited). Refer to Speed Limitations for more information. This CCC transmits the I3CxMWS, I3CxMRS, and I3CxMRT registers from the Target with the Most Significant bit first. The frame format is shown in Figure 1.
