Description
Must be written to 0x0F for proper operation.
A1 overrides the AV mute value with Bit 6.
Sets AV mute value if override is enabled.
Disables mute of video during AV mute.
Disables mute of audio during AV mute.
MCLK PLL enable—uses analog PLL.
MCLK PLL N [2:0]—this controls the division of the MCLK out of
the PLL: 0 = /1, 1 = /2, 2 = /3, 3 = /4, etc.
Prevents the N/CTS packet on the link from writing to the N and
CTS registers.
Controls the multiple of 128 f
1 = 256 f , 2 = 384, 7 = 1024 f
S
This disables the MDA/MCL pull-ups.
Clock termination power-down override: 0 = auto, 1 = manual.
Clock termination: 0 = normal, 1 = disconnected.
This bit resets the audio FIFO if underflow is detected.
This bit resets the audio FIFO if overflow is detected.
This bit three-states the MDA/MCL lines.
These 7 bits are updated if any specific packet has been received
since last reset or loss of clock detect. Normal is 0x00.

011 = reserved.
0 = software for which copyright is asserted.
1 = software for which no copyright is asserted.
0 = audio sample word represents linear PCM samples.
1 = audio sample word used for other purposes.
0 = consumer use of channel status block.
