0 = DVI, 1 = HDMI.
Mode = 00. All others are reserved.
When Bit 1 = 0 (linear PCM):
000 = 2 audio channels without pre-emphasis.
001 = 2 audio channels with 50/15 μs pre-emphasis.
010 = reserved.
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.
Clock accuracy.
00 = Level II.
01 = Level III.
10 = Level I.
11 = reserved.
0011 = 32 kHz.
0000 = 44.1 kHz.
1000 = 88.2 kHz.
1100 = 176.4 kHz.
0010 = 48 kHz.
1010 = 96 kHz.
1110 = 192 kHz.
Word length.
0000 = not specified.
0100 = 16 bits.
0011 = 17 bits.
0010 = 18 bits.
0001 = 19 bits.
0101 = 20 bits.
1000 = not specified.
1100 = 20 bits.
1011 = 21 bits.
1010 = 22 bits.
1001 = 23 bits.
1101 = 24 bits.
Cycle time stamp—this 20-bit value is used with the N
value to regenerate an audio clock. For remaining bits,
see Register 0x7C and Register 0x7D.
20-bit N used with CTS to regenerate the audio clock. For
remaining bits, see Register 0x7E and Register 0x7F.
ACP packets.
