__HAL_RCC_MCO1_CONFIG

#define __HAL_RCC_MCO1_CONFIG	(		__MCOCLKSOURCE__,
			__MCODIV__
	)		MODIFY_REG(RCC->CFGR, (RCC_CFGR_MCO1 | RCC_CFGR_MCO1PRE), ((__MCOCLKSOURCE__) | (__MCODIV__)))

Macro to configure the MCO1 clock.

Parameters

<strong>MCOCLKSOURCE</strong>	specifies the MCO clock source. This parameter can be one of the following values: RCC_MCO1SOURCE_HSI: HSI clock selected as MCO1 source RCC_MCO1SOURCE_LSE: LSE clock selected as MCO1 source RCC_MCO1SOURCE_HSE: HSE clock selected as MCO1 source RCC_MCO1SOURCE_PLLCLK: main PLL clock selected as MCO1 source
<strong>MCODIV</strong>	specifies the MCO clock prescaler. This parameter can be one of the following values: RCC_MCODIV_1: no division applied to MCOx clock RCC_MCODIV_2: division by 2 applied to MCOx clock RCC_MCODIV_3: division by 3 applied to MCOx clock RCC_MCODIV_4: division by 4 applied to MCOx clock RCC_MCODIV_5: division by 5 applied to MCOx clock

__HAL_RCC_MCO2_CONFIG

#define __HAL_RCC_MCO2_CONFIG	(		__MCOCLKSOURCE__,
			__MCODIV__
	)		MODIFY_REG(RCC->CFGR, (RCC_CFGR_MCO2 | RCC_CFGR_MCO2PRE), ((__MCOCLKSOURCE__) | ((__MCODIV__) << 3U)));

Macro to configure the MCO2 clock.

Parameters

<strong>MCOCLKSOURCE</strong>

specifies the MCO clock source. This parameter can be one of the following values: RCC_MCO2SOURCE_SYSCLK: System clock (SYSCLK) selected as MCO2 source RCC_MCO2SOURCE_PLLI2SCLK: PLLI2S clock selected as MCO2 source, available for all STM32F4 devices except STM32F410xx RCC_MCO2SOURCE_I2SCLK: I2SCLK clock selected as MCO2 source, available only for STM32F410Rx devices RCC_MCO2SOURCE_HSE: HSE clock selected as MCO2 source RCC_MCO2SOURCE_PLLCLK: main PLL clock selected as MCO2 source

<strong>MCODIV</strong>

specifies the MCO clock prescaler. This parameter can be one of the following values: RCC_MCODIV_1: no division applied to MCOx clock RCC_MCODIV_2: division by 2 applied to MCOx clock RCC_MCODIV_3: division by 3 applied to MCOx clock RCC_MCODIV_4: division by 4 applied to MCOx clock RCC_MCODIV_5: division by 5 applied to MCOx clock

Note

For STM32F410Rx devices, to output I2SCLK clock on MCO2, you should have at least one of the SPI clocks enabled (SPI1, SPI2 or SPI5).
