| 0x0-0x1 | Offset in shared-memory for the command to process immediately after this one, when not 0xFFFF. |
| 0x2-0x3 | CommandID |
| 0x4-0x7 | This is initially zero when this command data is written by the user process, once the CSND module finishes processing the command this is set to 0x1. |
| 0x8-0xB | ? |
| 0xC-0x1F | Command parameters |
Type0 Commands
Command 0xE
| Index Byte | Description |
|---|---|
| 0x2-0x3 | CmdID 0xE |
| 0x14-0x17 | Physical address for the audio data. |
