Enumeration Type Documentation

enum AFI2SBCBitLength

Possible I2S bit lengths list for AFI2SBusCap. Note: constant names should match their semantical values, i.e. BIT_X = X.

Enumerator:

BIT_8	8 bit length
BIT_16	16 bit length
BIT_24	24 bit length
BIT_32	32 bit length

Definition at line 64 of file AFI2SBus.h.

enum AFI2SBCDataAlign

Possible I2S data alignment list for AFI2SBusCap.

Enumerator:

LEFT_JUSTIFIED	Data is left justified.
RIGHT_JUSTIFIED	Data is right justified.
I2S	I2S alignment (MSB available on the 2nd rising edge).
DSP	DSP alignment (LR_CLK marks the start of a frame).

Definition at line 54 of file AFI2SBus.h.

enum AFI2SBCMode

Possible I2S modes list for AF I2S bus capabilities structure (AFI2SBusCap).

Enumerator:

MASTER	Master mode.
SLAVE	Slave mode.

Definition at line 47 of file AFI2SBus.h.

enum AFI2SBCSampleRate

Possible I2S sample frequencies list for AFI2SBusCap. Note: constant names should match their semantical values, i.e. FS_X = X.
