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.
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.
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.
0: Tamper 3 event erases the backup registers.
1: Tamper 3 event does not erase the backup registers.
