| CCC | 8-bit CCC code (when I3C acts as controller) |
| MTYPE | Message type (when I3C acts as controller) 6 (B_0x6_WHEN_I3C_ACTS_AS_I3C_CONTROLLER): broadcast/direct CCC command (refer to Table 540, Figure 658, Figure 659, Figure 660) |
| MEND | Message end type/last message of a frame (when I3C acts as controller) 0 (B_0x0): this message from controller is followed by a repeated start (Sr), before another message must be emitted 1 (B_0x1): the message from the controller ends with a stop (P), being the last message of a frame |
