Description
0 (default)
I2S 32 bit mode detected
1
I2S 64 bit mode detected
cs_bit_override
, TX2 Main Map,
Address 0xF40C[6]
This bit is used to select the source of channel status bits when using I2S Mode 4.
Function
cs_bit_override
Description
0 (default)
Use channel status bits from I2S stream
1
Use channel status bits programmed in I2C registers
audio_sampling_freq_sel
, TX2 Main Map,
Address 0xF40C[7]
This bit is used to select whether the audio sampling frequency is set automatically or manually (via I2C).
Function
audio_sampling_freq_sel
Description
0
