= RTCCLK / 32768
 RTC_TamperSamplingFreq_RTCCLK_Div16384 :
Each of the tamper inputs are sampled with a frequency
= RTCCLK / 16384
 RTC_TamperSamplingFreq_RTCCLK_Div8192 :
Each of the tamper inputs are sampled with a frequency
= RTCCLK / 8192
 RTC_TamperSamplingFreq_RTCCLK_Div4096 :
Each of the tamper inputs are sampled with a frequency
= RTCCLK / 4096
 RTC_TamperSamplingFreq_RTCCLK_Div2048 :
Each of the tamper inputs are sampled with a frequency
= RTCCLK / 2048
 RTC_TamperSamplingFreq_RTCCLK_Div1024 :
Each of the tamper inputs are sampled with a frequency
= RTCCLK / 1024
