Description:
This command configures enhanced configuration of the codec interface. This command is optional and cannot be used when all default parameters are acceptable. When this command is used, it must come after HCI_VS_Write_CODEC_Config.
| Command Parameter | Size | Value | Description |
|---|---|---|---|
| Clock shutdown | 1 |
0x00 0x01 |
PCM clock shutdown feature is disabled. PCM clock shutdown feature is enabled. Time of start/stop is defined in the following two fields (used in master mode only). |
| Clock start | 2 | 0x0000 – 0xFFFF | Number of PCM clock cycles relative to the PCM frame sync to start PCM clock (for example, start two clocks before frame sync) |
| Clock stop | 2 | 0x0000 – 0xFFFF | Number of PCM clock cycles relative to the PCM frame sync to stop PCM clock (for example, stop 20 clocks after frame sync) |
| Reserved | 1 | 0x00 | Default: 0x00 |

Data driven MSB first Data driven LSB first Don’t swap bytes within the sample. Swap bytes within the sample in bit-wise mode when data size > 8 ([XYZ]->[ZYX]). Do not shift the sample. Shift the sample by (24|16-dout_size) bits from MSB to LSB (controls sample alignment inside internal register (23:0) in bit-wise mode only). |
