◆ __HAL_RCC_I2S_CONFIG

#define __HAL_RCC_I2S_CONFIG ( __SOURCE__ )

Value:

                                             do {RCC->CFGR &= ~(RCC_CFGR_I2SSRC); \
                                             RCC->CFGR |= (__SOURCE__);       \
                                            }while(0)

Macro to configure the I2S clock source (I2SCLK).

Note: This function must be called before enabling the I2S APB clock.

Parameters

<strong>SOURCE</strong>

specifies the I2S clock source. This parameter can be one of the following values:

RCC_I2SCLKSOURCE_PLLI2S: PLLI2S clock used as I2S clock source.
RCC_I2SCLKSOURCE_EXT: External clock mapped on the I2S_CKIN pin used as I2S clock source.

◆ __HAL_RCC_PLLI2S_DISABLE

#define __HAL_RCC_PLLI2S_DISABLE ( ) (RCC->CR &= ~(RCC_CR_PLLI2SON))

◆ __HAL_RCC_PLLI2S_ENABLE

#define __HAL_RCC_PLLI2S_ENABLE ( ) (RCC->CR |= (RCC_CR_PLLI2SON))

Macros to enable or disable the PLLI2S.

Note: The PLLI2S is disabled by hardware when entering STOP and STANDBY modes.
