RTC tamper and alternate function configuration register
| TAMP1E | RTC_TAMP1 input detection enable |
| TAMP1TRG | Active level for RTC_TAMP1 input If TAMPFLT != 00 if TAMPFLT = 00: |
| TAMPIE | Tamper interrupt enable |
| TAMP2E | RTC_TAMP2 input detection enable |
| TAMP2TRG | Active level for RTC_TAMP2 input if TAMPFLT != 00: if TAMPFLT = 00: |
| TAMP3E | RTC_TAMP3 detection enable |
| TAMP3TRG | Active level for RTC_TAMP3 input if TAMPFLT != 00: if TAMPFLT = 00: |
| TAMPTS | Activate timestamp on tamper detection event TAMPTS is valid even if TSE=0 in the RTC_CR register. |
| TAMPFREQ | Tamper sampling frequency Determines the frequency at which each of the RTC_TAMPx inputs are sampled. |
| TAMPFLT | RTC_TAMPx filter count These bits determines the number of consecutive samples at the specified level (TAMP*TRG) needed to activate a Tamper event. TAMPFLT is valid for each of the RTC_TAMPx inputs. |
| TAMPPRCH | RTC_TAMPx precharge duration These bit determines the duration of time during which the pull-up/is activated before each sample. TAMPPRCH is valid for each of the RTC_TAMPx inputs. |
| TAMPPUDIS | RTC_TAMPx pull-up disable This bit determines if each of the RTC_TAMPx pins are pre-charged before each sample. |
| TAMP1IE | Tamper 1 interrupt enable |
| TAMP1NOERASE | Tamper 1 no erase |
| TAMP1MF | Tamper 1 mask flag |
| TAMP2IE | Tamper 2 interrupt enable |
| TAMP2NOERASE | Tamper 2 no erase |
| TAMP2MF | Tamper 2 mask flag |
| TAMP3IE | Tamper 3 interrupt enable |
| TAMP3NOERASE | Tamper 3 no erase |
| TAMP3MF | Tamper 3 mask flag |
