I2S / PCM Link Capabilities (I2SLCAP) – Offset d00
This register identifies the specific link associated capabilities.
| Bit Range | Default | Access | Field Name and Description |
|---|---|---|---|
| 31:28 | 1h | RO | Audio Link Type (ALT) Indicates which Link Type this link belongs to. |
| 27 | 1h | RO | Interrupt Capable (INTC) Indicates the link is capable of generating interrupt or not. |
| 26 | 1h | RO | Offload Support (OFLS) Indicates the link control offload is supported or not. |
| 25:24 | 0h | RO | Number of Serial Data Out Signals (NSDO) Indicates the number of Serial Data Output signal supported. |
| 23 | 1h | RO | Link Synchronization Support (LSS) Indicates whether the multiple sub-links synchronization is supported or not. |
| 22:20 | 2h | RO | Sub Link Count (SLCOUNT) Indicates the number of sub-links. Up to 8 sub-links can be supported. A '0' indicates 1 sub-link, and '111' indicates 8 sub-links. Note that this Sub Link Count is the cumulative total number of sub-links where the links are homogeneous and share a common link clock source allowing synchronization across the sub-links. |
| 19:6 | 0h | RO | Reserved (Zero) (RSVD19) SW must use zeros for writes. |
| 5 | 0h | RO | 192 MHz Supported (S192) Indicates 192 MHz clock is supported. |
| 4 | 0h | RO | 96 MHz Supported (S96) Indicates 96 MHz clock is supported (if set). |
| 3 | 0h | RO | 48 MHz Supported (S48) Indicates 48 MHz clock is supported (if set). |
| 2 | 0h | RO | 24 MHz Supported (S24) Indicates 24 MHz clock is supported (if set). |
| 1 | 0h | RO | 12 MHz Supported (S12) Indicates 12 MHz clock is supported (if set). |
| 0 | 0h | RO | 6 MHz Supported (S6) Indicates 6 MHz clock is supported (if set). |
