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 TEBX Bit is en-
abled while the device is in battery backup (see
set to logic '1' (Normally Open). In this case the
state of the TDSX Bit is a “Don’t care.”
Note: The crystal oscillator must be “On” for sam-
pling to be enabled.
Tamper Current Hi/Tamper Current Lo (TCHI/
TCLO1 and TCHI/TCLO2). This bit selects the
strength of the internal pull-up or pull-down used
during the sampling of the Normally Closed condi-
