Bit 3 – NOTIFY_IBI_REJECTED Notify Rejected In-Band Interrupt Request Control

Value	Name	Description
0	DISABLED	Do not pass rejected IBI status to the IBI queue/rings, if the incoming IBI is NACK’ed and is auto-disabled based on the IBI_REJECT field in relevant DAT entry.
1	ENABLED	Pass rejected IBI status to the IBI queue/rings, if the incoming IBI is NACK’ed and is auto-disabled based on the IBI_REJECT field in the relevant DAT entry.

Bit 1 – NOTIFY_CRR_REJECTED Notify Rejected Controller-role Request Control

Value	Name	Description
0	DISABLED	Do not pass rejected IBI status to IBI queue/ring, if the incoming controller-role request is NACK’ed and is auto-disabled based on the CRR_REJECT field in the relevant DAT entry.
1	ENABLED	Pass rejected IBI status to the IBI queue, if the incoming controller-role request is NACK’ed and is auto-disabled based on the CRR_REJECT field in the relevant DAT entry.

Bit 0 – NOTIFY_HJ_REJECTED Notify Rejected Hot-Join Control

Value	Name	Description
0	DISABLED	Do not pass rejected IBI status to IBI queue, if the incoming hot-join request is NACK’ed and is auto-disabled based on I3CC_HC_CONTROL.HOT_JOIN_CTRL.
1	ENABLED	Pass rejected IBI status to the IBI queue, if the incoming hot join request is NACK’ed and is auto-disabled based on I3CC_HC_CONTROL.HOT_JOIN_CTRL.
