4:2

BCLKDIV

000

Configures the BCLK and FRAME output frequency,

for use when the chip is master over BCLK.

000=divide by 1 (BCLK=MCLK)

001=divide by 2 (BCLK=MCLK/2)

010=divide by 4

011=divide by 8

100=divide by 16

101=divide by 32

110=reserved

111=reserved

Digital Audio

Interfaces

Reserved

Sets the chip to be master over FRAME and BCLK

0=BCLK and FRAME clock are inputs

1=BCLK and FRAME clock are outputs generated by

the WM8952 (MASTER)

SOFT_START

VMID Soft Start

0=disabled

1=enabled

POP Minimisation

TOGGLE

Fast VMID Discharge

0=normal

1=enable (used during power-down)

000

Approximate sample rate (configures the coefficients

for the internal digital filters):

000=48kHz

001=32kHz

010=24kHz

011=16kHz

100=12kHz

101=8kHz

110-111=reserved

SLOWCLKEN

Enables the Timeout Clock for zero cross detection.

Zero Cross

Timeout

00h

Reserved

MODE_GPIO

Selects MODE as a GPIO pin

0 = MODE is an input. MODE selects 2-wire mode

when low and 3-wire mode when high.

1 = MODE can be an input or output under the control

of the GPIO control register. Interface operates in 3-

wire mode regardless of when happens on the MODE

pin.

00=divide by 1

01=divide by 2

10=divide by 3

11=divide by 4
