Description:

		I3C’s Hot-Join mechanism allows an I3C Device to inform the

		Active Controller that a newly-joined Target is present on the

		I3C Bus and is ready to receive a Dynamic Address, in order to

		become fully functional on the Bus. Hot-Join is used when the

		Target is mounted on the same I3C bus and remains depowered

		until needed or until the Target is physically inserted into the

		I3C bus



		This entry allows to enable or disable Hot-join of the Current

		Controller driving the bus.
