Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

31:2

Bit	Name	Description	Access	Reset
31:2	`Reserved_31_2`	Reserved_31_2	`RO`	`0x0`
1	`ATS`	ATS implemented.When this bit is set to 0, the corresponding node is a TBU that is connected to the TCU using the DTI-TBU protocol.When this bit is set to 1, the corresponding node is a PCIe Root Complex that supports ATS, and is connected to the TCU using the DTI-ATS protocol.	`RO`	`0x0`
0	`CONNECTED`	DTI link connected.When this bit is set to 0, the DTI link for the corresponding node is not connected.When this bit is set to 1, the DTI link for the corresponding node is connected.If a DTI link is not connected, accesses to TBU registers are RAZ/WI. However, the state might change between reading this register and attempting to access the TBU.	`RO`	`0x0`
