0 = 48 kHz

1 = 44.1 kHz

[13:11]

Mult

Used to set the base rate multiplication factor:

0h = x1 (48kHz, 44.1kHz or less)

1h = x2 (96kHz, 88.2kHz, 32kHz)

2h = Reserved

3h = x4 (192kHz, 176.4kHz)

4h-7h = Reserved

[10:8]

Div

Used to set the base rate division factor:

0h = divide by 1 (48kHz, 44.1kHz)

1h = divide by 2 (24kHz, 22.05kHz)

2h = divide by 3 (16kHz, 32kHz)

3h = divide by 4 (11.025kHz)

4h = Reserved

5h = divide by 6 (8kHz)

6h = Reserved
