62 / 92 page ALC888S-VD Datasheet 7.1+2 Channel HD Audio Codec with Two Independent SPDIF Outputs 54 Track ID: JATR-2265-11 Rev. 1.2 8.22. Verb – Set Unsolicited Response Control (Verb ID=708h) Enables a widget to generate an unsolicited response. Table 54. Verb – Set Unsolicited Response Control (Verb ID=708h) Set Command Format Codec Response Format Bit [31:28] Bit [27:20] Bit [19:8] Payload Bit [7:0] Response [31:0] CAd=X Node ID=Xh Verb ID=708h EnableUnsol [7:0] 0’s for All Nodes ‘EnableUnsol’ in Command Bit[7:0] for NID=01h (GPIO in Audio Function Group), 14h~1Ch, 1Eh, 11h, 1Fh (Port A to H, CD-IN, SPDIF-OUT, SPDIF-OUT2 and SPDIF-IN) Bit Description 31:8 Reserved. Read as 0’s. 7 Enable Unsolicited Response. 0: Disable 1: Enable 6:4 Reserved. Read as 0’s. 3:0 Tag for Unsolicited Response. Tag[3:0] is defined by software to assign a 4-bit tag for nodes that are enabled to generate unsolicited responses. 8.23. Verb – Get Pin Sense (Verb ID=F09h) Returns the Presence Detect status and the impedance of a device attached to the pin. Table 55. Verb – Get Pin Sense (Verb ID=F09h) Get Command Format Codec Response Format Bit [31:28] Bit [27:20] Bit [19:8] Payload Bit [7:0] Response [31:0] CAd=X Node ID=Xh Verb ID= F09h 0’s 32-bit Response Codec Response for NID = 14h~1Bh, 11h, 1Eh, 1Fh Bit Description 31 Presence Detect Status. 0: No device is attached to the pin 1: Device is attached to the pin 30:0 Measured Impedance. The ALC888S-VD does not support hardware impedance detection. This field is read as 0s. Codec Response for Other NID Bit Description 31:0 Not Supported (Returns 00000000h). |
