Macro Definition Documentation

__HAL_SAI_CLEAR_FLAG

#define __HAL_SAI_CLEAR_FLAG	(		__HANDLE__,
			__FLAG__ )

Value:

((__HANDLE__)->Instance->CLRFR = (__FLAG__))

Clear the specified SAI pending flag.

Parameters

__HANDLE__

specifies the SAI Handle.

__FLAG__

specifies the flag to check. This parameter can be any combination of the following values: SAI_FLAG_OVRUDR: Clear Overrun underrun SAI_FLAG_MUTEDET: Clear Mute detection SAI_FLAG_WCKCFG: Clear Wrong Clock Configuration SAI_FLAG_FREQ: Clear FIFO request SAI_FLAG_CNRDY: Clear Codec not ready SAI_FLAG_AFSDET: Clear Anticipated frame synchronization detection SAI_FLAG_LFSDET: Clear Late frame synchronization detection

Return values

None

__HAL_SAI_DISABLE

#define __HAL_SAI_DISABLE

(

__HANDLE__

)

Value:

((__HANDLE__)->Instance->CR1 &=  ~SAI_xCR1_SAIEN)

Disable SAI.

Parameters

__HANDLE__

specifies the SAI Handle.

Return values

None

__HAL_SAI_DISABLE_IT

#define __HAL_SAI_DISABLE_IT	(		__HANDLE__,
			__INTERRUPT__ )

Value:

((__HANDLE__)->Instance->IMR &= (~(__INTERRUPT__)))

__HAL_SAI_ENABLE

#define __HAL_SAI_ENABLE

(

__HANDLE__

)

Value:

((__HANDLE__)->Instance->CR1 |=  SAI_xCR1_SAIEN)

Value:

((__HANDLE__)->Instance->IMR |= (__INTERRUPT__))

Enable the specified SAI interrupts.

Parameters

__HANDLE__

specifies the SAI Handle.

__INTERRUPT__
