Terminology

See also Section 2 in the MIPI I3C Specification [MIPI01][MIPI10][MIPI12].

Definitions

ACK: Short for “acknowledge” (an I3C Bus operation)
Bus Available: I3C Bus condition in which a Device is able to initiate a transaction on the Bus.
Bus Free: I3C Bus condition after a STOP and before a START with a duration of at least tCAS.
Bus Idle: An extended duration of the Bus Free condition in which Devices may attempt to Hot-Join the I3C Bus.
High-Keeper: A weak Pull-Up type Device used when SDA, and sometimes SCL, is in High-Z with respect to all Devices.
Hot-Join: Slaves that join the I3C Bus after it is already started, whether because they were not powered previously or because they were physically inserted into the Bus. The Hot-Join mechanism allows the Slave to notify the Master that it is ready to get a Dynamic Address.
In-Band Interrupt (IBI): A method whereby a Slave Device emits its Address into the arbitrated Address header on the I3C Bus to notify the Master of an interrupt.
Main Master: Master that has initial control of the I3C Bus.
Master: The I3C Bus Device that is controlling the Bus.
Slave: An I3C Slave Device can only respond to either Common or individual commands from a Master. A Slave Device cannot generate a clock.
