Serial Audio DAC Interface
The serial audio DAC interface is a Synchronous Peripheral Interface (SPI) in slave mode:
•
•
•
Note:
Figure 15-6. Serial Audio Interface
Protocol is as following to access DAC registers:
AUDCDIN: is used to transfer data in series from the master to the slave DAC.
It is driven by the master.
AUDCDOUT: is used to transfer data in series from the slave DAC to the master.
It is driven by the selected slave DAC.
Serial Clock (AUDCCLK): it is used to synchronize the data transmission both in and out the
devices through the AUDCDIN and AUDCDOUT lines.
