Specifications
Serial audio interface
This section includes information about the audio interface.
The serial-to-parallel interface and the parallel-to-serial interface can have different
sampling rates.
The following terms are used in this section:
●
●
BICLK active edge: Pins SDATAI, SDATAO, LRCLKI, LRCLKO always change
synchronously with BITCLK active edges. The active edge can be configured to a rising
or falling edge via register programming.
BICLK strobe edge: Pins SDATAI, SDATAO, LRCLKI, LRCLKO should be stable near
BICLK strobe edges, the slave device is able to use strobe edges to latch serial data
internally.
