Response Format:
Bits [15:0] must be programmed with the same value programmed into the Stream Descriptor, so that the
data format being transmitted on the link matches what is expected by the consumer of the data.
If the TYPE is set to Non-PCM, the controller pushes data over the link and is not concerned with format-
ting. The base rate, data type, and number of Words (MULT) to send each valid frame are specified to
control the rate at which the non-PCM data is sent.

Description
Reserved
Stream Type (TYPE): If TYPE is non-zero, the
other bits in the format structure have other
meanings.
0: PCM
1: Non-PCM
Sample Base Rate (BASE):
0 = 48 kHz
1 = 44.1 kHz
Sample Base Rate Multiple (MULT):
000 = 48 kHz/44.1 kHz or less
001 = x2 (96 kHz, 88.2 kHz, 32 kHz)
010 = x3 (144 kHz)
011 = x4 (192 kHz, 176.4 kHz)
100-111 = Reserved
Sample Base Rate Divisor (DIV):
000 = Divide by 1 (48 kHz, 44.1 kHz)
001 = Divide by 2 (24 kHz, 22.05 kHz)
010 = Divide by 3 (16 kHz, 32 kHz)
011 = Divide by 4 (11.025 kHz)
100 = Divide by 5 (9.6 kHz)
101 = Divide by 6 (8 kHz)
110 = Divide by 7
111 = Divide by 8 (6 kHz)
Reserved
Bits per Sample (BITS): Bits in each sample:
000 = 8 bits. The data will be packed in memory
in 8-bit containers on 16-bit boundaries.
001 = 16 bits. The data will be packed in memory
in 16-bit containers on 16-bit boundaries.
010 = 20 bits. The data will be packed in memory
in 32-bit containers on 32-bit boundaries.
011 = 24 bits. The data will be packed in memory
in 32-bit containers on 32-bit boundaries.
100 = 32 bits. The data will be packed in memory
in 32-bit containers on 32-bit boundaries.
101-111 = Reserved
Number of Channels (CHAN): Number of chan-
nels in each frame of the stream:
0000 = 1
0001 = 2
…
1111 = 16
