6.14 I²S Controller with Internal Audio CODEC (I²S)
6.14.1 Overview
The I²S controller consists of I²S protocol interface to internal audio CODEC and supports to use
external audio CODEC. The I²S controller includes two 16 words FIFO for transfer path and
receiver path respectively and is capable of handling 8, 16, 24, or 32 bits word sizes sample.
The structure of internal audio CODEC is a delta-sigma 24-bit CODEC with microphone input,
audio line-in input, and headphone output.
