5.7.2 I3C In-band Interrupts

The device supports the in-band interrupt (IBI) feature of I3C, as described in the I3C specification. In case there is an IBI

event, the device will emit its address into the arbitrated address header following a START (but not following a repeated

START).

If no START is forthcoming within the Bus Available Condition, then the chip will actively pull down the SDA line to issue

a START. The IBI feature can be enabled by the Common Command Code (CCC)’ ENEC with the ENINT bit set to

0b1.The IBI feature can be disabled by the Common Command Code (CCC)’ DISEC with the DISINT bit set to 0b1.

Upon power up, the feature is disabled by default. The IBI mandatory byte is defined in Table 24. This is also the IBI

payload that will be returned upon an GETSTATUS CCC command.

More information on the meaning of the interrupts can be found in section 4.7 "Interrupts".
