Intel® Core™ Ultra Processors for H-series and U-series Platforms SOC I/O Registers
Link x 96 MHz Input Payload Capability (LINPAY960) – Offset c78
This register identifies the specific link associated capabilities.
Bit Range | Default | Access | Field Name and Description |
---|---|---|---|
15:0 | 0h | RO/V | Input Payload Capability (LINPAY96) Indicates the total input payload available on the link at 96 MHz frequency. This does not include bandwidth used for response. This measurement is in 16-bit word quantities per 48 kHz frame.Note that this value does not reflect any bandwidth increases due to support for multiple SDI lines.For iDISPLAY Audio Link, the optional nT mode enabling in theory will reduce the input bandwidth available, however, since input streams are not supported for iDISPLAY Audio Link, the register value will always be zero.00h: 0 words01h: 1 word payloadFFh: 255h word payloadThe audio bus driver queries this lookup register and LPSIO to derive potential nett input bandwidth before deciding whether to switch frequency. |
