Maximum Write/Read Speed

The Maximum Write Speed and Maximum Read Speed are the maximum sustained data rate for non-Common Command Code (CCC) messages transacted between the Controller and the Target. This Target module can sustain a transfer rate at up to the maximum allowable FSCL frequency of 12.5 MHz. However, the user can set a slower read/write frequency based on the specific application using the I3CxMWS Maximum Write Speed and I3CxMRS Maximum Read Speed registers. The Controller can be notified of the slower frequency by setting the BCR0 bit during setup to signify that the device is speed-limited. After the Controller reads the I3CxBCR register during the Dynamic Address Assignment process, the Controller can then read the I3CxMWS and I3CxMRS registers using the Get Maximum Data Speed (GETMXDS) CCC.
