◆ DataSize

uint32_t SAI_InitTypeDef::DataSize

Specifies the SAI Block data size. This parameter can be a value of SAI Block Data Size

Definition at line 120 of file stm32f7xx_hal_sai.h.

◆ FIFOThreshold

uint32_t SAI_InitTypeDef::FIFOThreshold

Specifies SAI Block FIFO threshold. This parameter can be a value of SAI Block Fifo Threshold

Definition at line 94 of file stm32f7xx_hal_sai.h.

◆ FirstBit

uint32_t SAI_InitTypeDef::FirstBit

Specifies whether data transfers start from MSB or LSB bit. This parameter can be a value of SAI Block MSB LSB transmission

Definition at line 123 of file stm32f7xx_hal_sai.h.

◆ Mckdiv

uint32_t SAI_InitTypeDef::Mckdiv

Specifies the master clock divider. This parameter must be a number between Min_Data = 0 and Max_Data = 15.

Note: This parameter is used only if AudioFrequency is set to SAI_AUDIO_FREQUENCY_MCKDIV otherwise it is internally computed.

Specifies the master clock divider. This parameter must be a number between Min_Data = 0 and Max_Data = 63.

Note: This parameter is used only if AudioFrequency is set to SAI_AUDIO_FREQUENCY_MCKDIV otherwise it is internally computed.

Definition at line 100 of file stm32f7xx_hal_sai.h.

◆ MckOutput

uint32_t SAI_InitTypeDef::MckOutput

Specifies whether master clock output will be generated or not. This parameter can be a value of SAI Block Master Clock Output

Note: This feature is only available on STM32H7xx Rev.B and above

Definition at line 95 of file stm32h735/stm32h735g-dk/Drivers/STM32H7xx_HAL_Driver/Inc/stm32h7xx_hal_sai.h.

◆ MckOverSampling

uint32_t SAI_InitTypeDef::MckOverSampling

Specifies the master clock oversampling. This parameter can be a value of SAI Block Master Clock OverSampling

Definition at line 123 of file stm32h735/stm32h735g-dk/Drivers/STM32H7xx_HAL_Driver/Inc/stm32h7xx_hal_sai.h.

◆ MonoStereoMode

uint32_t SAI_InitTypeDef::MonoStereoMode

Specifies if the mono or stereo mode is selected. This parameter can be a value of SAI Mono Stereo Mode

Definition at line 105 of file stm32f7xx_hal_sai.h.

◆ NoDivider

uint32_t SAI_InitTypeDef::NoDivider

Specifies whether master clock will be divided or not. This parameter can be a value of SAI Block NoDivider

Note: : If bit NODIV in the SAI_xCR1 register is cleared, the frame length should be aligned to a number equal to a power of 2, from 8 to 256. If bit NODIV in the SAI_xCR1 register is set, the frame length can take any of the values without constraint since the input clock of the audio block should be equal to the bit clock. There is no MCLK_x clock which can be output.

If bit NODIV in the SAI_xCR1 register is set, the frame length can take any of the values from 8 to 256.; The NODIV bit is the same as NOMCK bit in STM32H7xx rev.Y

Definition at line 85 of file stm32f7xx_hal_sai.h.

◆ OutputDrive

uint32_t SAI_InitTypeDef::OutputDrive

Specifies when SAI Block outputs are driven. This parameter can be a value of SAI Block Output Drive

Note: this value has to be set before enabling the audio block but after the audio block configuration.
