For the AFG, PS-Act will equal PS-Set (offset by the time required to execute a power state transition). [3:0] PS-Set RW 2h Sets the power state of the AFG node: 0h = D0 1h = D1 2h = D2 3h = D3 4h = D4 Note: If the Link is operational, but the AFG is in power state D4, only Get Commands, Set Power State or AFG Reset commands are executed – all other commands are ignored. In this scenario, the SDI line is inactive and does not transmit responses, tags or data. UNSOLICITED RESPONSE VERB Verb ID Payload [7:0] Response[31:0] Get F08h 00h Bits [31:0] in the table below Set 708h Bits [7:0] in the table below 00000000h Bit Bitfield Name RW Default Description [31:8] Rsvd R 000000h Reserved [7] Enable RW 0 0 = Unsolicited Responses disabled for this node 1 = Unsolicited Responses enabled for this node [6] Rsvd R 0 Reserved [5:0] Tag RW 01h A software programmable tag value that is returned in the top six bits (31:26) of every Unsolicited Response from this node. The default for Tag is equal to the Node ID. Note: The Unsolicited Response for the AFG node is defined in the “Unsolicited Responses” section. |
