This bit disables the inter MDA/MCL pull-ups.
This bit resets the audio FIFO if underflow is detected.
3
This bit makes it possible to prevent the N/CTS packet
on the link from writing to the N and CTS registers.
2-0
These bits control the multiple of 128 fs used for
MCLK out.
6
5
This bit allows for overriding during power down.
0 = auto, 1 = manual.
4
This bit allows normal clock termination or
disconnects this. 0 = normal, 1 = disconnected.
2
1
This bit resets the audio FIFO if overflow is detected.
0
This bit three-states the MDA/MCL lines to allow in-
circuit programming of the EEPROM.
6-0
This register indicates if a data packet in specific
sections has been detected. These seven bits are
updated if any specific packet has been received since
last reset or loss of clock detect. Normal is 0x00.
