Bit 26 TAMP3TRG: Active level for tamper 3 input
0:If TAMPFLT ≠ 00 Tamper 3 input staying low triggers a tamper detection event.
If TAMPFLT = 00 Tamper 3 input rising edge and high level triggers a tamper detection
event.
1:If TAMPFLT ≠ 00 Tamper 3 input staying high triggers a tamper detection event.
If TAMPFLT = 00 Tamper 3 input falling edge and low level triggers a tamper detection
event.
