In I3C v1.1, use of this CCC is expanded to support Bridging Devices that have Dynamic Addresses, which makes multiple Bridging Devices on the same I3C Bus possible. The context of the SETBRGTGT CCC is also redefined: a Bridging Device is now one of several types of Devices that expose or present Virtual Targets. Bit[4] of the Target’s Bus Configuration Register (BCR) now indicates Virtual Target capabilities.

For bridged Targets that are enabled by a Bridging Device, I3C v1.1 clarifies the use of other CCCs (such as SETMRL) that address a bridged Target. The I3C v1.1 specification also clarifies that to change the Dynamic Address of a bridged Target, the SETBRGTGT CCC (not the SETNEWDA CCC) must be used.

For details, see the I3C v1.1 specification at Sections 5.1.1.2.1, 5.1.9.3.17, and 5.1.9.3.19.
