Bits Type Default Description

31:16 Read Only 0000h Reserved

15 Read/Write 0b

Stream Type (TYPE): If TYPE is non-zero, the

other bits in the format structure have other

meanings.

0: PCM

1: Non-PCM

14 Read/Write 0b

Sample Base Rate (BASE):

0 = 48 kHz

1 = 44.1 kHz

13:11 Read/Write 000b

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

10:8 Read/Write 000b

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)

7 Read Only 0b Reserved

6:4 Read/Write 000b

Bits per Sample (BITS): Number of 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

3:0 Read/Write 0000b

Number of Channels (CHAN): Number of chan-

nels in each frame of the stream:

0000 = 1

0001 = 2

…

1111 = 16

1 2 ... 70 71 72 73 74 75 76 77 78 79 80 ... 147 148
