5. Function Description
5.1 Standard Application System
Figure 5.1 shows a standard S1V3S344 application system. The host controls the S1V3S344 with commands
(message protocol) issued via the serial interface. After Power On Reset, the S1V3S344 outputs audio from the
internal DA converter while internally decode-processing the compressed audio data from the internal audio data
flash memory or issued from the host.
For details of commands, refer to S1V3034x Series Message Protocol Specification and Flash Access
