Field Documentation

FrameLength

uint32_t SAI_FrameInitTypeDef::FrameLength

Specifies the Frame length, the number of SCK clocks for each audio frame. This parameter must be a number between Min_Data = 8 and Max_Data = 256.

Note

If master clock MCLK_x pin is declared as an output, the frame length should be aligned to a number equal to power of 2 in order to keep in an audio frame, an integer number of MCLK pulses by bit Clock.

ActiveFrameLength

uint32_t SAI_FrameInitTypeDef::ActiveFrameLength

Specifies the Frame synchronization active level length. This Parameter specifies the length in number of bit clock (SCK + 1) of the active level of FS signal in audio frame. This parameter must be a number between Min_Data = 1 and Max_Data = 128

FSDefinition

uint32_t SAI_FrameInitTypeDef::FSDefinition

Specifies the Frame synchronization definition. This parameter can be a value of SAI Block FS Definition
