#define __HAL_RCC_CRS_AUTOMATIC_CALIB_DISABLE ( ) CLEAR_BIT(CRS->CR, CRS_CR_AUTOTRIMEN)

Enable or disable the automatic hardware adjustement of TRIM bits.

Return values:

None

Definition at line 2359 of file stm32l4xx_hal_rcc_ex.h.

#define __HAL_RCC_CRS_AUTOMATIC_CALIB_ENABLE ( ) SET_BIT(CRS->CR, CRS_CR_AUTOTRIMEN)

Enable the automatic hardware adjustement of TRIM bits.

Note:: When the AUTOTRIMEN bit is set the CRS_CFGR register becomes write-protected.

Return values:

None

Definition at line 2353 of file stm32l4xx_hal_rcc_ex.h.

#define __HAL_RCC_CRS_FREQ_ERROR_COUNTER_DISABLE ( ) CLEAR_BIT(CRS->CR, CRS_CR_CEN)

Disable the oscillator clock for frequency error counter.

Return values:

None

Definition at line 2346 of file stm32l4xx_hal_rcc_ex.h.

#define __HAL_RCC_CRS_FREQ_ERROR_COUNTER_ENABLE ( ) SET_BIT(CRS->CR, CRS_CR_CEN)

Enable the oscillator clock for frequency error counter.

Note:: when the CEN bit is set the CRS_CFGR register becomes write-protected.

Return values:

None

Definition at line 2340 of file stm32l4xx_hal_rcc_ex.h.

#define __HAL_RCC_CRS_RELOADVALUE_CALCULATE	(	__FTARGET__,
		__FSYNC__
	)	(((__FTARGET__) / (__FSYNC__)) - 1U)

Macro to calculate reload value to be set in CRS register according to target and sync frequencies.

Note:: The RELOAD value should be selected according to the ratio between the target frequency and the frequency of the synchronization source after prescaling. It is then decreased by one in order to reach the expected synchronization on the zero value. The formula is the following: RELOAD = (fTARGET / fSYNC) -1

Parameters:

__FTARGET__	Target frequency (value in Hz)
__FSYNC__	Synchronization signal frequency (value in Hz)

Return values:

None
