__STATIC_INLINE void LL_RTC_CAL_ConfigCoarseDigital
(RTC_TypeDef * RTCx, uint32_t Sign, uint32_t Value)
Set the coarse digital calibration.
RTCx: RTC Instance
Sign: This parameter can be one of the following values:
LL_RTC_CALIB_SIGN_POSITIVE
LL_RTC_CALIB_SIGN_NEGATIVE
Value: value of coarse calibration expressed in ppm (coded
on 5 bits)
None:
Bit is write-protected. LL_RTC_DisableWriteProtection
function should be called before.
It can be written in initialization mode only
(LL_RTC_EnableInitMode function)
This Calibration value should be between 0 and 63 when
using negative sign with a 2-ppm step.
This Calibration value should be between 0 and 126 when
using positive sign with a 4-ppm step.
