Figure 16. Basic Tamper Detect Options
Tamper Detect Sampling (TDS1 and TDS2).
This bit selects between a 1Hz sampling rate or
constant monitoring of the Tamper Input Pin(s) to
detect a tamper event when the Normally Closed
switch mode is selected. This allows the user to re-
duce the current drain when the TEB
X
Bit is en-
abled while the device is in battery backup (see
Table 4., page 17
and
Figure 17., page 18
). Sam-
pling is disabled if the TCM
X
Bit is set to logic '1'
(Normally Open). In this case the state of the
TDS
X
Bit is a “Don’t care.”
Note:
The crystal oscillator must be “On” for sam-
pling to be enabled.
