Serial 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:
Master mode
In this mode, pins BICLKI/BICLKO and pins LRCLKI/LRCLKO are configured as outputs.

Symbol
BICLK active edge: Pins SDATAI, SDATAO, LRCLKI, LRCLKO always change
synchronously with BITCLK active edges. The active edge can be configured as 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.
LRCLKI/LRCLKO propagation delay from BICLK active
edge
SDATAO propagation delay from BICLKI/O active edge 0
SDATAI setup time to BICLKI/O strobing edge
SDATAI hold time from BICLKI/O strobing edge
