#define ARM_SAI_FRAME_LENGTH | ( |  | n | ) | ((((n)-1)&0x3FFU) << ARM_SAI_FRAME_LENGTH_Pos)

Frame length in bits (8..1024); default depends on protocol and data.

#define ARM_SAI_FRAME_SYNC_WIDTH | ( |  | n | ) | ((((n)-1)&0xFFU) << ARM_SAI_FRAME_SYNC_WIDTH_Pos)

Frame Sync width in bits (1..256); default=1; User Protocol only (ignored otherwise)

#define ARM_SAI_FRAME_SYNC_POLARITY_HIGH (0U << ARM_SAI_FRAME_SYNC_POLARITY_Pos)

Frame Sync is active high (default); User Protocol only (ignored otherwise)

#define ARM_SAI_FRAME_SYNC_POLARITY_LOW (1U << ARM_SAI_FRAME_SYNC_POLARITY_Pos)

Frame Sync is active low; User Protocol only (ignored otherwise)

#define ARM_SAI_FRAME_SYNC_EARLY (1U << 19)

Frame Sync one bit before the first bit of the frame; User Protocol only (ignored otherwise)
