5.8.6.2. In-Band Interrupt (IBI)

The I3C controller protocol also provides support of in-band interrupts (IBI) within the two-wire interface, which reduces the device pin count and signal paths. The in-band interrupt is initiated by the I3C controller slave device to the current master.

Additionally, the I3C controller uses in-band interrupt for generating mastership request to request bus ownership.
