Common Command Code (CCC)

Common Command Codes (CCCs) are globally supported standardized commands that the Controller can transmit either directly to a specific target or broadcast to all targets on the bus simultaneously. The CCC protocol is formatted using I3C SDR and always begins with the I3C Broadcast Address (7’h7E/W). All I3C targets on the bus recognize this address, whereas any I2C target present on the bus will NACK the request since 7’h7E is a reserved I2C address.
