SoundWire x PCM Stream Capabilities (SNDW0PCMSCAP) – Offset 30010
This register identifies the SoundWire PCM stream capabilities.
The index (lowest to highest) of these PCM stream related registers are ordered starting from input stream per ISS, followed by output stream per OSS, followed by bi-directional stream per BSS.
| Bit Range | Default | Access | Field Name and Description |
|---|---|---|---|
| 15:13 | 0h | RO | Reserved (Zero) (RSVD15) SW must use zeros for writes. |
| 12:8 | fh | RO | Number of Bidirectional Streams Supported (BSS) Indicates the number of bidirectional PCM streams that the link supports. |
| 7:4 | 0h | RO | Number of Output Streams Supported (OSS) Indicates the number of output PCM streams that the link supports. |
| 3:0 | 0h | RO | Number of Input Streams Supported (ISS) Indicates the number of input PCM streams that the link supports. |
