Transmit FIFO level
These bits indicate word number in transmit FIFO
0000 = No data
0001 = 1 word in transmit FIFO
….
1000 = 8 words in transmit FIFO
Receive FIFO level
These bits indicate word number in receive FIFO
0000 = No data
0001 = 1 word in receive FIFO
….
1000 = 8 words in receive FIFO
Left channel zero cross flag
It indicates left channel next sample data sign bit is changed or all data bits are zero.
1 = Left channel zero cross is detected
0 = No zero cross
Software can write 1 to clear this bit to zero
Right channel zero cross flag
It indicates right channel next sample data sign bit is changed or all data bits are zero.
1 = Right channel zero cross is detected
0 = No zero cross
Software can write 1 to clear this bit to zero
