The CCCs are the commands that an I3C Master uses to communicate to some or all of the Slaves on the I3C bus. The CCCs are sent to the I3C broadcast address (which is 7’h7E) so as not to interfere with normal messages sent to a Slave. The CCCs are used for standard operations like enabling/disabling events, managing I3C specific features and other bus operations. CCCs can be either broadcasted (sent to all the devices on the bus), or directed at specific devices on the bus. All CCCs (i.e., the command numbers) are allocated by MIPI Alliance, with some reserved for specific purposes that include MIPI Alliance enhancements and vendor extensions.
