DESCRIPTION
R513 (0201h)
AIF 1
Clocking (2)
5:3
AIF1DAC_DIV
000
Selects the AIF1 input path sample rate
relative to the AIF1 output path sample
rate.
This field should only be changed from
default in modes where the AIF1 input
path sample rate is slower than the AIF1
output path sample rate.
000 = Divide by 1
001 = Divide by 1.5
010 = Divide by 2
011 = Divide by 3
100 = Divide by 4
101 = Divide by 5.5
110 = Divide by 6
111 = Reserved
2:0
AIF1ADC_DIV
000
Selects the AIF1 output path sample rate
relative to the AIF1 input path sample
rate.
This field should only be changed from
default in modes where the AIF1 output
path sample rate is slower than the AIF1
input path sample rate.
000 = Divide by 1
001 = Divide by 1.5
010 = Divide by 2
011 = Divide by 3
100 = Divide by 4

AIF1 Rate
7:4
AIF1_SR
1000
Selects the AIF1 Sample Rate (fs)
0000 = 8kHz
0001 = 11.025kHz
0010 = 12kHz
0011 = 16kHz
0100 = 22.05kHz
0101 = 24kHz
0110 = 32kHz
0111 = 44.1kHz
1000 = 48kHz
1001 = 88.2kHz
1010 = 96kHz
All other codes = Reserved
Note that 88.2kHz and 96kHz modes are
supported for AIF1 input (DAC playback)
only.
3:0
AIF1CLK_RAT
E
0011
Selects the AIF1CLK / fs ratio
0000 = Reserved
0001 = 128
0010 = 192
0011 = 256
0100 = 384
0101 = 512
0110 = 768
0111 = 1024
1000 = 1408
1001 = 1536
