21.1 Introduction
The I
ADCs/DACs, and the ARM Core. It consists of 3 transmitter channels and 3 receiver
channels. Each channel handles a single stereo stream. The transmitter and receiver are
completely independent of each other and are programmed separately. Each channel (RX
and TX) has its own set of addressable registers which allows access through the ARM APB
or DMA accesses.

The i2s_audioclk_mux section performs gating on the incoming audio clocks based on the
settings within the TX and RX clock configuration registers and delivers a known clock
definition to the rest of the I
