SoundWire x Wake Status (SNDW2WAKESTS) – Offset 4600a
This register reports wake status.
| Bit Range | Default | Access | Field Name and Description |
|---|---|---|---|
| 15:1 | 0h | RO | Reserved (Zero) (RSVD15) SW must use zeros for writes. |
| 0 | 0h | RW/1C | PREQ/WakeUp Status (PWS) This bit is set when SoundWire Data input state is high and the PREQ/WakeUp Wake Enable bit = 1. Use case is to enable monitoring of SoundWire Data input only after SoundWire Bus has been put into ClockStop and Manager IP has been put into context lost state (power removed.) Under this state, '1' value on this bit indicates a remote-initiated WakeUp interrupt and propagate to SoC (LCTL.OFLEN = 0) or DSP Core (LCTL.OFLEN = 1) as wake cause on behalf of the device. |
