Tamper and backup registers (TAMP) RM0440
1586/2126 RM0440 Rev 4
36.6.3 TAMP filter control register (TAMP_FLTCR)
Address offset: 0x0C
Backup domain reset value: 0x0000 0000
System reset: not affected
Bits 22:19 Reserved, must be kept at reset value.
Bit 18 TAMP3MSK: Tamper 3 mask
0: Tamper 3 event generates a trigger event and TAMP3F must be cleared by software to
allow next tamper event detection.
1: Tamper 3 event generates a trigger event. TAMP3F is masked and internally cleared by
hardware. The backup registers are not erased.
The tamper 3 interrupt must not be enabled when TAMP3MSK is set.
Bit 17 TAMP2MSK: Tamper 2 mask
0: Tamper 2 event generates a trigger event and TAMP2F must be cleared by software to
allow next tamper event detection.
1: Tamper 2 event generates a trigger event. TAMP2F is masked and internally cleared by
hardware. The backup registers are not erased.
The tamper 2 interrupt must not be enabled when TAMP2MSK is set.
Bit 16 TAMP1MSK: Tamper 1 mask
0: Tamper 1 event generates a trigger event and TAMP1F must be cleared by software to
allow next tamper event detection.
1: Tamper 1 event generates a trigger event. TAMP1F is masked and internally cleared by
hardware. The backup registers are not erased.
The tamper 1 interrupt must not be enabled when TAMP1MSK is set.
Bits 15:3 Reserved, must be kept at reset value.
Bit 2 TAMP3NOER: Tamper 3 no erase
0: Tamper 3 event erases the backup registers.
1: Tamper 3 event does not erase the backup registers.
Bit 1 TAMP2NOER: Tamper 2 no erase
0: Tamper 2 event erases the backup registers.
1: Tamper 2 event does not erase the backup registers.
Bit 0 TAMP1NOER: Tamper 1 no erase
0: Tamper 1 event erases the backup registers.
1: Tamper 1 event does not erase the backup registers.
