STA310

Type: R/W

Software Reset: 0x34

Hardware Reset: UND

Description:

This register must contain a FRACL value that en-

ables the audio PLL to generate a frequency of

ofact*192KHz for the PCMCK.

Default value at soft reset assume:

– Oversampling factor (ofact) = 384. PCMLCK =

384 x SF (where SF is the sampling frequency)

– External crystal provide a clock running at

27MHz

AU_PLL_FRACH_192

Frac High Coefficient

Address: 0xB7

Type: R/W

Software Reset: 0xEC

Hardware Reset: UND

Description:

This register must contain a FRACH value that en-

ables the audio PLL to generate a frequency of

ofact*192KHz for the PCMCK.

Default value at soft reset assume:

– Oversampling factor (ofact) = 384. PCMLCK =

384 x SF (where SF is the sampling frequency)

– External crystal provide a clock running at

27MHz

AU_PLL_XDIV_192

X Divider Coefficient

Address: 0xB8

Type: R/W

Software Reset: 0x01

Hardware Reset: UND

Description:

This register must contain a XDIV value that enables

the

audio

PLL

generate

frequency

ofact*192KHz for the PCMCK.

Default value at soft reset assume:

– Oversampling factor (ofact) = 384. PCMLCK =

384 x SF (where SF is the sampling frequency)

– External crystal provide a clock running at

27MHz

AU_PLL_MDIV_192

M Divider Coefficient

Address: 0xB9

Type: R/W

Software Reset: 0x09

Hardware Reset: UND

Description:

This register must contain a MDIV value that enables

the

audio

PLL

generate

frequency

ofact*192KHz for the PCMCK.

Default value at soft reset assume:

– Oversampling factor (ofact) = 384. PCMLCK =

384 x SF (where SF is the sampling frequency)

– External crystal provide a clock running at

27MHz

AU_PLL_NDIV_192

N Divider Coefficient

Address: 0xBA

Type: R/W

Software Reset: 0x01

Hardware Reset: UND

Description:

This register must contain a NDIV value that enables

the

audio

PLL

generate

frequency

ofact*192KHz for the PCMCK.

Default value at soft reset assume:

– Oversampling factor (ofact) = 384. PCMLCK =
