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.
