Public Types Documentation¶

enum Peripheral¶

Enumerator	Value	Description
SAI_1
SAI_2

Specifies the internal peripheral to use (mapped to different hardware pins)

enum SampleRate¶

Enumerator	Value	Description
SAI_8KHZ
SAI_16KHZ
SAI_32KHZ
SAI_48KHZ
SAI_96KHZ

Rate at which samples will be streaming to/from the device.

enum BitDepth¶

Enumerator	Value	Description
SAI_16BIT
SAI_24BIT
SAI_32BIT

Bit Depth that the hardware expects to be transferred to/from the device.

enum Sync¶

Enumerator	Value	Description
MASTER
SLAVE

Specifies whether a particular block is the master or the slave If both are set to slave, no MCLK signal will be used, and it is expected that the codec will have its own xtal.

enum Direction¶

Enumerator	Value	Description
TRANSMIT
RECEIVE

Specifies the direction for each peripheral block.
