Description
1: Falling edge trigger a tamper detection event
3
TP2EN
Tamper 2 detection enable
0: Disable tamper detection
1: Enable tamper detection
2
TPINTEN
Tamper event interrupt enable.
0: Disable tamper interrupt
1: Enable tamper interrupt
Note: This bit enables the interrupt of all tamper pins events, regraadless of
TPxINTEN level. If this bit is cleared, each tamper event interrupt can be individually
enabled by setting TPxINTEN.
1
TP1TRG
Tamper 1 event trigger edge
if TPFLT[1:0] != 00, tamper detection is in level mode:
0: low level trigger a tamper detection event.
1: high level trigger a tamper detection event.
if TPFLT = 00, tamper detection is in edge mode:
0: Rising edge trigger a tamper detection event.
1: Falling edge trigger a tamper detection event
0
TP1EN
Tamper 1 detection enable
0: Disable tamper detection
1: Enable tamper detection

MASKSSB[3:0]
Mask the most significant bit from this bits.
0x0: No comparison on sub seconds for Alarm. The alarm is set when the seconds unit
is incremented (assuming that the rest of the fields match).
0x1: Only SSV[0] is compared and other bits are not compared.
0x2: Only SSV[1:0] are compared and other bits are not compared.
0x3: Only SSV[2:0] are compared and other bits are not compared.
