Figure 4. Layers performed by embedded DSP firmware
The whole CDROM and file-system decoding task is performed by embedded firmware. The application MCU,
basically, must manage CDDSP device according to STA016A requests. Three basic command flows exist:

MCU -> STA016A: commands used to handle decoder operation and to ask for specific information like
filename, filelength, sector raw data, etc. This flow will use I
STA016A -> MCU: this channel is used to retrieve inquired information and to inform MCU that a
CDDSP specific operation must be performed (like pick-up repositioning). This flow is based on I
plus an additional interrupt signal in order to avoid time consuming polling techniques.
MCU -> CDDSP: the CDDSP management is fully up to the application MCU. This architecture allows
maximum flexibility and easy migration from existing CDPlayers to MP3 CDPlayers.
