TAMP active tamper control register 1
| TAMP1AM | Tamper 1 active mode 0 (B_0x0): Tamper 1 detection mode is passive. 1 (B_0x1): Tamper 1 detection mode is active. |
| TAMP2AM | Tamper 2 active mode 0 (B_0x0): Tamper 2 detection mode is passive. 1 (B_0x1): Tamper 2 detection mode is active. |
| ATOSEL1 | Active tamper shared output 1 selection The selected output must be available in the package pinout 0 (B_0x0): TAMPOUTSEL1 = TAMP_OUT1 1 (B_0x1): TAMPOUTSEL1 = TAMP_OUT2 2 (B_0x2): TAMPOUTSEL1 = TAMP_OUT3 3 (B_0x3): no value |
| ATOSEL2 | Active tamper shared output 2 selection The selected output must be available in the package pinout 0 (B_0x0): TAMPOUTSEL2 = TAMP_OUT1 1 (B_0x1): TAMPOUTSEL2 = TAMP_OUT2 2 (B_0x2): TAMPOUTSEL2 = TAMP_OUT3 3 (B_0x3): no value |
| ATOSEL3 | Active tamper shared output 3 selection The selected output must be available in the package pinout 0 (B_0x0): TAMPOUTSEL3 = TAMP_OUT1 1 (B_0x1): TAMPOUTSEL3 = TAMP_OUT2 2 (B_0x2): TAMPOUTSEL3 = TAMP_OUT3 3 (B_0x3): no value |
| ATCKSEL | Active tamper RTC asynchronous prescaler clock selection These bits selects the RTC asynchronous prescaler stage output. The selected clock is CK_ATPRE. f CK_ATPRE = f RTCCLK / 2supATCKSEL /supwhen (PREDIV_A+1) = 128. … Note: These bits can be written only when all active tampers are disabled. The write protection remains for up to 1.5 CK_ATPRE cycles after all the active tampers are disable. 0 (B_0x0): RTCCLK is selected 1 (B_0x1): RTCCLK/2 is selected when (PREDIV_A+1) = 128 (actually selects 1supst/sup flip flop output) 2 (B_0x2): RTCCLK/4 is selected when (PREDIV_A+1) = 128 (actually selects 2supnd/sup flip flop output) 7 (B_0x7): RTCCLK/128 is selected when (PREDIV_A+1) = 128 (actually selects 7supth/sup flip flop output) |
| ATPER | Active tamper output change period The tamper output is changed every CK_ATPER = (2supATPER /supx CK_ATPRE) cycles. Refer to Table 239: Minimum ATPER value. |
| ATOSHARE | Active tamper output sharing TAMP_IN1 is compared with TAMPOUTSEL1 TAMP_IN2 is compared with TAMPOUTSEL2 TAMP_IN3 is compared with TAMPOUTSEL3 TAMP_IN4 is compared with TAMPOUTSEL4 TAMP_IN5 is compared with TAMPOUTSEL5 TAMP_IN6 is compared with TAMPOUTSEL6 TAMP_IN7 is compared with TAMPOUTSEL7 TAMP_IN8 is compared with TAMPOUTSEL8 0 (B_0x0): Each active tamper input TAMP_INi is compared with its dedicated output TAMP_OUTi 1 (B_0x1): Each active tamper input TAMP_INi is compared with TAMPOUTSELx as defined below, with TAMPOUTSELx defined by ATOSELx bits. |
| FLTEN | Active tamper filter enable 0 (B_0x0): Active tamper filtering disable 1 (B_0x1): Active tamper filtering enable: a tamper event is detected when 2 comparison mismatches occur out of 4 consecutive samples. |
