Description
Mode = 00. All others are reserved.
When Bit 1 = 0 (linear PCM):
000 = two audio channels without pre-emphasis.
001 = two audio channels with 50 μs/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.
