__STATIC_INLINE void LL_RTC_CAL_SetCoarseDigital	(	BKP_TypeDef *	BKPx,
		uint32_t	Value
	)

Set the coarse digital calibration.

Note:

Bit is write-protected. LL_RTC_DisableWriteProtection function should be called before.

It can be written in initialization mode only (LL_RTC_EnterInitMode function)

Reference Manual to LL API cross reference:

RTCCR CAL LL_RTC_CAL_SetCoarseDigital

Parameters:

BKPx	RTC Instance
Value	value of coarse calibration expressed in ppm (coded on 5 bits)

Note:

This Calibration value should be between 0 and 121 when using positive sign with a 4-ppm step.

Return values:

None
