Each audio channel is comprised of 32 bits of data, regardless of audio sample size. The
figure above shows 24-bit audio data.
The MSB is left justified and is aligned with FS1. Data is sampled on the rising edge of
DAI_SCLK and data changes on the falling edge.
Each audio channel is comprised of 32 bits of data, regardless of audio sample size. The
figure above shows 24-bit audio data.
The MSB is left justified and arrives one bit period following FS1. Data is sampled on the
rising edge of DAI_SCLK and data changes on the falling edge.
