The master clock frequency must be either 128x, 256x, 384x or 512x the input sample rate in Base Rate
Mode (BRM) and either 64x, 128x, 192x, or 256x the input sample rate in High Rate Mode (HRM). Table
2 illustrates several standard audio sample rates and the required master clock frequencies. The
MCLK/Fs ration is set by the CI1:0 bits in the CODEC Clock Mode register
Clocks serial control data into or out of SDA/CDIN.
In I
open drain output operation. In SPI mode, CDIN is the control port data input line. The state of the SDOUT
pin during reset is used to set the control port mode.
In I
interface.
When low, the device enters a low power mode and all internal registers are reset to the default settings,
including the control port. The control port can not be accessed when reset is low.
When high, the control port and the CODEC become operational.

C mode, AD0 is the LSB of the chip address. In SPI mode, CS is used as a enable for the control port
C mode, SDA is a bidirectional control port data line. A pull up resistor must be provided for proper
