I3C has several Modes, each with associated bit rate(s). The base raw bitrate is 12.5 Mbps, with 11 Mbps real data rate at 12.5 MHz clock frequency (this is the only Mode supported in I3C v1.0 and I3C Basic v1.0). The maximum raw bitrate is 33.3 Mbps at 12.5 Mhz, with real data rate of 30 Mbps; this is achieved via HDR Modes that are currently only available in I3C v1.0.

Most traffic will use the 10 to 11 Mbps rate, while large messages can use one of the higher data rate Modes.
