37.2.7.2.2 Enter Dynamic Address Assignment (ENTDAA)

The Controller uses the Broadcast ENTDAA CCC to indicate to all I3C devices on the bus to enter the Dynamic Address Assignment procedure as described in Dynamic Address Assignment. The Target module will participate in this procedure unless it already has a Dynamic Address assigned, in which case the Target NACKs this command and waits for the next Start condition. The ENTDAA CCC always ends with a Stop condition (not Restart). The frame format for Broadcast Write ENTDAA CCC is shown in Figure 37-24.

Important: The Target's response to ENTDAA CCC depends on whether it is a Hot-Joining device or not (HJCAP bit) as explained in the Hot-Join Mechanism section.
